Bug description

After transferring ownership of files (if Object storage is configured as primary), they do not appear in web-interface. Though outgoing shares still can be discovered via Shares => Shared with others

Steps to reproduce

0. Configure object storage to be used as primary (reproduced with Minio)

As user1

1. make outgoing shares with different users (user2, user3, e.t.c)
2. move one of the shared files to trashbin
3. transfer files to one of these users (e.g. user2)

occ -v files:transfer-ownership --transfer-incoming-shares=0 --path "/" user1 user2

see output:

Validating quota
Analysing files of user1 ...

Collecting all share information for files and folders of user1 ...

Transferring files to user2/ ...
Restoring shares ...
1/4 [=======>--------------------] 25% < 1 sec
Share with id 1 points at deleted file, skipping
Share with id 3 points at deleted file, skipping
4/4 [============================] 100% < 1 sec

in oc_filecache see that parent set to -1 for all transferred files

Expected behavior

parent should be === fileid of directort specified during tranfer => user2/files in example
