    BSE: ignore warnings for remotely disconnected signals that are already disconnected
    
    One possible scenario the old behavior could trigger bogus warnings is if
    BSE still keeps track of closure and tries to disconnect after they have been
    auto-disconnected by g_object_run_dispose.
