Peter Wilson 8cd24bc12c Administration: Prevent an orderby array throwing a notice.
Prevent `WP_List_Table::search_box()` from throwing an array to string conversion notice when post list tables are loaded with an array of orderby parameters in the URL, eg: `/wp-admin/edit.php?post_type=page&orderby[menu_order]=ASC&orderby[title]=ASC`.

Follow up to [29027].
