    properties-window: use app info for "Open With" visibility
    
    We were special casing desktop icon files to not show the Open With
    tab in the properties window.
    
    However, this is just equal to what we need to do to display Open With
    in the context menus, where we check if the app has a possible
    application handling it or not.
    
    Do the same here so we can remove another desktop dependency.
