    gtestdbus: Clarify comment on dropping connection ref
    
    In _g_object_unref_and_wait_weak_notify() we take a weak reference and
    then call g_object_unref() in an idle callback, which may look like
    we're dropping a strong reference without having one. So change the
    comment to make it more clear that the reference being dropped is held
    by the caller.
