webdav: don't delete files on error - fixes #3263

Previous to this change rclone deleted a file if the upload failed
half way through.

After this change we only delete the upload if the
--webdav-delete-on-error flag is set.

We set this in the serve webdav tests to make them pass.

 If you find a bug that you'd like to fix, or a new feature that you'd
 like to implement then please submit a pull request via GitHub.

+If it is a big feature then make an issue first so it can be discussed.
 
-To prepare your pull request first press the fork button on [rclone's GitHub
+You'll need a Go environment set up with GOPATH set.  See [the Go
+getting started docs](https://golang.org/doc/install) for more info.
+
+First in your web browser press the fork button on [rclone's GitHub
 page](https://github.com/rclone/rclone).
 
-Then [install Git](https://git-scm.com/downloads) and set your public contribution [name](https://docs.github.com/en/github/getting-started-with-github/setting-your-username-in-git) and [email](https://docs.github.com/en/github/setting-up-and-managing-your-github-user-account/setting-your-commit-email-address#setting-your-commit-email-address-in-git).

-    cd rclone

+    cd $GOPATH/src/github.com/rclone/rclone

-      # otherwise:
-    git remote add origin https://github.com/YOURUSER/rclone.git
 
-Note that most of the terminal commands in the rest of this guide must be executed from the rclone folder created above.
-
-Now [install Go](https://golang.org/doc/install) and verify your installation:
-
-    go version
-
-Great, you can now compile and execute your own version of rclone:
-
-    go build
-    ./rclone version
-
-(Note that you can also replace `go build` with `make`, which will include a
-more accurate version number in the executable as well as enable you to specify
-more build options.) Finally make a branch to add your new feature

 Note that you may need to make a test remote, e.g. `TestSwift` for some
 of the unit tests.

+Note the top level Makefile targets
+

-## Using Git and GitHub ##
-
-### Committing your changes ###
-
-Follow the guideline for [commit messages](#commit-messages) and then:
-
-    git checkout my-new-feature      # To switch to your branch
-    git status                       # To see the new and changed files
-    git add FILENAME                 # To select FILENAME for the commit
-    git status                       # To verify the changes to be committed
-    git commit                       # To do the commit
-    git log                          # To verify the commit. Use q to quit the log
-
-You can modify the message or changes in the latest commit using:
-
-    git commit --amend
-
-If you amend to commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Replacing your previously pushed commits ###
-
-Note that you are about to rewrite the GitHub history of your branch. It is good practice to involve your collaborators before modifying commits that have been pushed to GitHub.
-
-Your previously pushed commits are replaced by:
-
-    git push --force origin my-new-feature 
-
-### Basing your changes on the latest master ###
-
-To base your changes on the latest version of the [rclone master](https://github.com/rclone/rclone/tree/master) (upstream):
-
-    git checkout master
-    git fetch upstream
-    git merge --ff-only
-    git push origin --follow-tags    # optional update of your fork in GitHub
-    git checkout my-new-feature
-    git rebase master
-
-If you rebase commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-### Squashing your commits ###
-
-To combine your commits into one commit:
-
-    git log                          # To count the commits to squash, e.g. the last 2
-    git reset --soft HEAD~2          # To undo the 2 latest commits
-    git status                       # To check everything is as expected
-

-It is quite easy to add a new S3 provider to rclone.

-You'll need to modify the following files
-
-- `backend/s3/s3.go`
-    - Add the provider to `providerOption` at the top of the file
-    - Add endpoints and other config for your provider gated on the provider in `fs.RegInfo`.
-    - Exclude your provider from genric config questions (eg `region` and `endpoint).
-    - Add the provider to the `setQuirks` function - see the documentation there.
-- `docs/content/s3.md`
-    - Add the provider at the top of the page.
-    - Add a section about the provider linked from there.
-    - Add a transcript of a trial `rclone config` session
-        - Edit the transcript to remove things which might change in subsequent versions
-    - **Do not** alter or add to the autogenerated parts of `s3.md`
-    - **Do not** run `make backenddocs` or `bin/make_backend_docs.py s3`
-- `README.md` - this is the home page in github
-    - Add the provider and a link to the section you wrote in `docs/contents/s3.md`
-- `docs/content/_index.md` - this is the home page of rclone.org
-    - Add the provider and a link to the section you wrote in `docs/contents/s3.md`
-
-When adding the provider, endpoints, quirks, docs etc keep them in
-alphabetical order by `Provider` name, but with `AWS` first and
-`Other` last.
-
-Once you've written the docs, run `make serve` and check they look OK
-in the web browser and the links (internal and external) all work.
-
-Once you've written the code, test `rclone config` works to your
-satisfaction, and check the integration tests work `go test -v -remote
-NewS3Provider:`. You may need to adjust the quirks to get them to
-pass. Some providers just can't pass the tests with control characters
-in the names so if these fail and the provider doesn't support
-`urlEncodeListings` in the quirks then ignore them. Note that the
-`SetTier` test may also fail on non AWS providers.
-
-For an example of adding an s3 provider see [eb3082a1](https://github.com/rclone/rclone/commit/eb3082a1ebdb76d5625f14cedec3f5154a5e7b10).

-
-To show the current lifecycle rules:
-
-    rclone backend lifecycle b2:bucket

-If there are no lifecycle rules (the default) then it will just return [].

-
-    rclone backend lifecycle b2:bucket -o daysFromHidingToDeleting=30
-    rclone backend lifecycle b2:bucket -o daysFromUploadingToHiding=5 -o daysFromHidingToDeleting=1
