Versions not moved when moving file into shared folder as recipient

[PVince81]

Steps

1. Create a user "user1"
2. Create a folder "folder"
3. Share "folder" with "user1"
4. Login as "user1"
5. Create a file "test.txt" in the root
6. Edit "test.txt" several times to create versions
7. Move "test.txt" into "folder"

Expected result

Versions copied properly from "user1/files_versions" to "root/files_versions/folder"

Actual result

Versions stay in "user1/files_versions"

At the time where the versions are moved, the wrong absolute path is used. It uses "user1" in both even though the target should be relative to "root".

Okay, it looks like this is a very old undiscovered bug. Saw it happening on stable7 too.

Fixed through #15881
