Issue #3263201 by manuel.adan: Missing argument type on hook_shortcut_default_set declaration

 * modules implement this hook, the last (i.e., highest weighted) module which

 * returns a valid shortcut set name will prevail.

 *

 * @param $account

 * @param \Drupal\Core\Session\AccountInterface $account

 *   The user account whose default shortcut set is being requested.

 *

 * @return string

 *   The name of the shortcut set that this module recommends for that user, if

 *   there is one.
