dropbox: make sure we wait for previous batch to finish before starting a new one

If you exceed rate limits, dropbox tells you to wait for 300 seconds -
this is rather a long time for the user to be waiting for rclone to
finish, so emit a NOTICE level log instead of a DEBUG.

-First make the release branch.  If this is a second point release then
+Set vars
-this will be done already.
 
   * 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
