[gnome-menus/wip/gobject-review: 12/38] Lower gmenu_tree_item_get_parent to gmenu_tree_directory_get_parent

[Vincent Untz <vuntz src gnome org>]

    Lower gmenu_tree_item_get_parent to gmenu_tree_directory_get_parent
    
    Introspection doesn't know about the GMenuTreeItem "subclassing",
    so we would have to duplicate the _get_parent method on all
    subclasses - but in practice it only seems to be used on directories,
    so just lower it there.
