Replace duplicate code

     // Lock the collection
        if ($view->get_collection()) {
            $collectionid = $view->get_collection()->get('id');
            execute_sql("UPDATE {collection} SET lock = 1 WHERE id = ?", array($collectionid));
        }

with the new function in lib/collection.php
