Can't delete a group that was provisioned, and has a field with provisioningGroupWrapper.thisGroupPrivilegeHolders('updaters', 'entityAttributeValueCache0'). It creates rows in grouper_sync_dep_group_group, which don't get cleaned up before deleting the group.

Caused by: Error : 2292, Position : 0, SQL = delete from grouper_groups where id=:1 and hibernate_version_number=:2 , Original SQL = delete from grouper_groups where id=? and hibernate_version_number=?, Error Message = ORA-02292: integrity constraint (GROUPER.GROUPER_SYNC_DEP_GRP_GRP_FK_1) violated - child record found

Deleting the rows manually from this table fixes it, and the group can now be deleted.
