Ticket 49278 - GetEffectiveRights gives false-negative
Bug: If geteffective rights was issued for an non existing entry the

Fix: Improve the handling in itreating the result set, so that template entries (if
requested) are genereated and are not applied to existing entries.
Also some code cleanup in iterate()
