    nautilus-file-utilities: Add GVolumeMonitor auto cleanup
    
    In nautilus_get_mounted_mount_for_root
    g_volume_monitor_get is called
    without cleanup
    
    We need cleanup or auto cleanup
    for GVolumeMonitor
    
    g_autoptr is added for auto cleanup
    
    Closes https://gitlab.gnome.org/GNOME/nautilus/issues/471
