Unsharing federated folder causes reuploading the part of it by the sync client

[VicDeo]

reproduced on stable10 with/without OCM changes:

0. Setup a sync client for user2
1. user1 shares an empty folder to user2.
2. user2 adds 2 subfolders
3. wait for the sync client
4. user1 revokes the access the the folder
5. wait for the sync client

on the step 5 sync client recreates the folder and partially uploads content

user2 unshared the folder E (213M)
jah-mobile:~/public_html/stable10dup> du -hd0 data/user2/files/
8.0K data/user2/files/

On the next sync:
jah-mobile:~/public_html/stable10dup> du -hd0 data/user2/files/
38M data/user2/files/

Note: it was reproduced twice and now works as expected :/

currently hard to reproduce, might need more data from whoever is able to ?

let's try for another 0.5md to reproduce this and hope for more luck

as we had no luck reproducing, will need to wait for more info
