2cd1f96c Fixes that a condition, to keep redundancy groups in the result
(as they cannot be subjected to restrictions), lead to expensive and
irrelevant sub-queries in cases where redundancy groups were not
fetched. (e.g. usergroups)
6cb15efc Changes restriction application so that restrictions of
multiple roles are merged together instead of being processed
individually. This helps the ORM to generate less sub-queries and I
suspect performance will also be improved, even if just slightly.
