    apps-menu: 'Touch' copied .desktop file after updating attributes
    
    At least for now, nautilus' file monitor is blind to certain metadata
    updates:
    https://git.gnome.org/browse/nautilus/tree/src/nautilus-mime-actions.c#n1537
    
    So in order for the changes in the previous patch to take effect
    immediately, we need to force nautilus to reload the file info.
    Achieve this by updating the access time of the newly copied file
    after marking it as trusted.
