[gnome-settings-daemon/benzea/minor-fix-collection: 47/51] power, color: Use g_signal_connect_object for the session manager

    power,color: Use g_signal_connect_object for the session manager
    
    The session manager object is globally shared and may live longer than
    the GSD plugin manager object. Use g_signal_connect_object rathre than
    g_signal_connect to prevent callbacks to destroyed objects.
    
    This is a theoretical issue, no impact has been seen from this.
