If I clone an object I would assume that any update of it will result an INSERT in the DB (along
with INSERTs for all relations!). As "clone" is just a special case of "new" I don't understand why
you would need the "original" UID. Actually I wouldn't mind if update() on a new or cloned object
would trigger an error or raise an exception.
