Followup to the previous commit

It was actually rather simple to make sure depsgraph is up to date
before calling BKE_object_handle_update() in the transform code by
just moving DAG_scene_relations_update() to the beginning of the
function.

Wouldn't expect any side effects for other cases since DAG is not
used bu the code between new location of the call and old one.
