[entity] don't look at fetch order recursively If fetch_attrs includes relations, stop including the entities on the other side in our sorting. Fixes regression from 73ea636a5562 where we would sort on the target entity before the attribute we wanted if the relation's name sorted before the attribute's. This showed up in the forge/tracker cubes with Version entities being sorted by their State's name in preference to their version number.
