    load-more-button: Simplify signal handlers tracking
    
    Use g_signal_connect_object() to make sure that signals are disconnected
    when the toolbar is destroyed and use g_signal_handlers_disconnect_by_func()
    otherwise.
    
    This allows us to get rid of all the signal id member fields.
