    libmenu: Clear cache of desktop entries set when files are added/removed
    
    When installing or removing an application, we get a notification of
    change. However, the menu tree still contained the same content.
    
    We were simply not clearing the cache containing the list of desktop
    entries when a file got added or removed, meaning that we always got the
    same list of desktop entries.
    
    (Note that it didn't affect gnome-panel, it's unclear why)
