Minor fixes needed for generic key name We no longer try to retreive an entity when there are unset fields. This sort of makes 'getIfFields' obsolete, since we check if fields now anyway. This is needed because getKeyFieldsFromDict expects the fields to be set. Also a minor fix in a Django template so that the generic 'edit' page has a working delete button again.
