[QA] cannot delete folders; rename duplicates folders

Seen while testing files_external_s3-2.0.0 with owncloud core 10.11.0-rc.1 Also seen in files_external_s3-1.0.0 with core 10.10.0 - not a regression.

Configure an external storage using a scality s3 server

Using the Web UI:

create a subfolder logs in /s3-bucket
add a file into /s3-bucket/logs/
rename the subfolder 'logs' to 'renamed' - the rename seems to succeed. The contens is there.
shift reload the web UI. The 'logs' folder appears next to 'renamed'. BAD.
contents is in both folders. BAD.
no error messages are logged. BAD.

try to delete the folder 'logs' in '/s3-bucket'. An error appears: 'Error deleting file "logs"'. BAD

Workaround:
* use `s3cmd del --recursive ...` to really remove folders.

It makes no difference, if the folder was empty.
Files can be deleted without problems, though.
