Fix version rename with files and folders

[PVince81]

• fix moving folder into another folder (note: I observed this on stable7, stable8 and master!)
• fix moving file or folder into shared folder as recipient (Versions not moved when moving file into shared folder as recipient #15867)

Please review @schiesbn @nickvergessen @icewind1991

@karlitschek we might want to backport this: moving a folder loses the versions of all contained files when moved into another folder, happens on stable7 and stable8.

[karlitschek]

yes. please backport after 8.0.3 👍

[schiessle]

looks good 👍

[rullzer]

Looking good! 👍
Tested both scenarios and working!

I'm having problems with versions via webdav but that is also on master. So this is unrelated.

@rullzer versions via WebDAV ? There is no such thing in ownCloud. Still curious to hear how you did it 😄

[PVince81]

I'll take care of the backport to stable8.
@karlitschek you didn't specify whether you also agreed with a stable7 backport as it is losing versions there too.
