Erroneous folder duplication

[nfebe]

The sftp-service or one of the api's it depends on, would sometimes fail to recognize an existing folder it created in the remote (permanent) and end up creating duplicates of the same folder.

How to reproduce

Colon (:) case

• Run rclone copy -vv path/to/local/source/directory "local:/archives/ots-dev (0001-0000)/My Files/10-10:30"
  • Take note about the name of the destination folder "10-10:30" at end of the remote specification, so introducing a colon (:) into the name would lead the reproduction of this bug. It has currently been tested with numbers and letters so something like A:B would equally lead to the demonstration of this bug.
• Reproduce via permaent-rclone-qa
  • Run the ./upload-test.py command with the neccesary parameters as described in permanent-rclone-qa upload tests and specify a --remote-dir that has colon for example --remote-dir=10-10:30 or --remote-dir=A:B
  • Example test-tree/special-files/10-10KB/ --remote-dir=10-10-9:40 --log-file=log-10-1KB.txt --remote=local --archive-path="/archives/ots-dev (0001-0000)/My Files/"
