we need a middle-man method to convert the unique "assessment-session"
            authority question_ids into "real" itemIds
        BUT this also has to return the "magic" item, so we can't rely
        on
                question = self.get_question(question_id)
                ils = self._get_item_lookup_session()
                return ils.get_item(Id(question._my_map['itemId']))
