    GtkDialog: Connect to activate signals only once
    
    If the widget is an action widget, it's been previously added with
    gtk_dialog_add_action_widget, which calls add_response_data on it, which
    in turn connects to the clicked/activate signal of that widget, so we
    don't need to connect to that signal a second time in
    gtk_buildable_custom_finished.
