    app: treat an empty ("" not NULL) plug-in proc_install->menu_path as NULL
    
    gimp_plug_in_handle_proc_install(): don't set the new procedure's menu
    path nor its menu label if proc_install->menu_path is "", so we don't
    run into action and menu creating confusion later. Do it here and not
    later so the "" string never enters the system.
