Is the fix in one of the unlanded patches for ~~LU-4684~~?

This is a bug in migration code: if migrating file has link, and if the parent of the link is the same as source object parent, it will deadlock, because the source object parent was locked already, and herein it tries to lock again. I've fixed this issue in ~~LU-4684~~, so maybe it's not necessary to fix it since dir migration is not officially supported yet.
