Server: Offer duplicate/rename when copying into same folder

[tobiasKaminsky]

In webUI

• create 1.txt
• select copy/move on 1.txt
• select "/" as target for copy
  -> fails with "error 1.txt already exists"

Instead it should offer a rename dialog with "suggest new name", so that one can duplicate the file with a new name.

Currently I have to do this c&p manually on desktop (android also refuses this).

Does this make sense? Then I'll open up an issue also on android/test on iOS.

GitMate.io thinks possibly related issues are https://github.com/nextcloud/server/issues/553 (Issues after renaming an already shared folder...), https://github.com/nextcloud/server/issues/6491 (Duplicate Shared folders), https://github.com/nextcloud/server/issues/9152 (Problem renaming folders), https://github.com/nextcloud/server/issues/8628 (renaming shared folder - no actualization), and https://github.com/nextcloud/server/issues/9957 (Critical: renaming files inside shared nested folder duplicates file).

Isn't this already targeted by #10825 which automatically adds ([Xth] copy) to files copied to the same directory?
