Copying a file via client with an already existing name to a dropbox backend mount causes issues

[mmattel]

Referenced client issue: owncloud/client#6947

Expected behaviour

Copying a file with an already existing name to a DropBox backend mount should work without any error.

Actual behaviour

Copying a file with an already existing name to a DropBox backend mount causes an error which will vanish after some minutes.

Steps to reproduce

1. mount a DB as backend and sync it thru the client
2. copy a file with an existing name into the sync (file/foldername has no issues)
3. wait and watch
