vfs: fix saving from chrome without --vfs-cache-mode writes

Due to Chrome's rather complicated use of file handles when saving
files from the download windows, rclone was attempting to truncate a
closed file.

The file appeared closed due to the handling of 0 length files.

This patch removes the check for the file being closed in the
WriteFileHandle.Truncate call. This is safe because the only action
this method takes is to emit an error message if the file is the wrong
size.

See: https://forum.rclone.org/t/google-drive-cannot-save-files-directly-from-browser-to-gdrive-mounted-path/17992/

+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).

-## 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
-
-If everything is fine, then make the new combined commit:
-
-    git commit                       # To commit the undone commits as one
-
-otherwise, you may roll back using:
-
-    git reflog                       # To check that HEAD{1} is your previous state
-    git reset --soft 'HEAD@{1}'      # To roll back to your previous state
-
-If you squash commits that have been pushed to GitHub, then you will have to [replace your previously pushed commits](#replacing-your-previously-pushed-commits).
-
-Tip: You may like to use `git rebase -i master` if you are experienced or have a more complex situation.
-
-### GitHub Continuous Integration ###
+## CI for your fork ##
 
 rclone currently uses [GitHub Actions](https://github.com/rclone/rclone/actions) to build and test the project, which should be automatically available for your fork too from the `Actions` tab in your repository.
 
 ## Testing ##
 
-### Quick testing ###

 level you can run this to run all the tests.

-    bin/tidy-beta v1.55

+    * GO111MODULE=on go mod tidy
+ 
 
 ## Making a point release
 
 If rclone needs a point release due to some horrendous bug:
 
-Set vars
-
-  * BASE_TAG=v1.XX          # e.g. v1.52
-  * NEW_TAG=${BASE_TAG}.Y   # e.g. v1.52.1
-  * echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
-
 First make the release branch.  If this is a second point release then
 this will be done already.
 
-  * git co -b ${BASE_TAG}-stable ${BASE_TAG}.0
-  * make startstable
+  * BASE_TAG=v1.XX          # eg v1.52
+  * NEW_TAG=${BASE_TAG}.Y   # eg v1.52.1
+  * echo $BASE_TAG $NEW_TAG # v1.52 v1.52.1
+  * git branch ${BASE_TAG} ${BASE_TAG}-stable
 
 Now
 
   * git co ${BASE_TAG}-stable
   * git cherry-pick any fixes
-  * Do the steps as above
-  * make startstable
+  * Test (see above)
+  * make NEXT_VERSION=${NEW_TAG} tag
+  * edit docs/content/changelog.md
+  * make TAG=${NEW_TAG} doc
+  * git commit -a -v -m "Version ${NEW_TAG}"
+  * git tag -d ${NEW_TAG}
+  * git tag -s -m "Version ${NEW_TAG}" ${NEW_TAG}
+  * git push --tags -u origin ${BASE_TAG}-stable
+  * Wait for builds to complete
+  * make BRANCH_PATH= TAG=${NEW_TAG} fetch_binaries
+  * make TAG=${NEW_TAG} tarball
+  * make TAG=${NEW_TAG} sign_upload
+  * make TAG=${NEW_TAG} check_sign
+  * make TAG=${NEW_TAG} upload
+  * make TAG=${NEW_TAG} upload_website
+  * make TAG=${NEW_TAG} upload_github
+  * NB this overwrites the current beta so we need to do this
   * git co master
-  * `#` cherry pick the changes to the changelog - check the diff to make sure it is correct
-  * git checkout ${BASE_TAG}-stable docs/content/changelog.md
-  * git commit -a -v -m "Changelog updates from Version ${NEW_TAG}"
+  * make VERSION=${NEW_TAG} startdev
+  * # cherry pick the changes to the changelog and VERSION
+  * git checkout ${BASE_TAG}-stable VERSION docs/content/changelog.md
+  * git commit --amend
   * git push
+  * Announce!
 
 ## Making a manual build of docker
 
 The rclone docker image should autobuild on via GitHub actions.  If it doesn't
 or needs to be updated then rebuild like this.
