    main: Fix media player controls not appearing in gnome-shell
    
    Media player controls in gnome-shell wouldn't appear if totem was first
    launched normally, and a video selected afterwards, but would work if
    one double-clicked on a file.
    
    The problem was that the controls would only show if the CanPlay MPRIS
    property was set to true, and the plugin would only change that property
    if it received a property notification for an MRL being set. Nothing
    was sending that property notification though.
    
    One line later, the property is sent, and the MPRIS plugin works whether
    or not totem was opened with a double-click.
    
    Closes: #208
