Describe the bug

Removing a federated share does not update the resource's share-types.

Steps to reproduce

1. Share a file that has no shares and links with a federated user
2. Do a PROPFIND on the resource -> oc:share-types includes 0
3. Remove the federated share
4. Do a PROPFIND on the resource again -> oc:share-types still includes 0

Expected behavior

share-types should be empty.

Actual behavior

share-types still includes 0
