Public bug reported:

We have an external app that creates Views in Mahara. While creating
Views it creates the corresponding layout if needed. However, an error
was alwasys thrown at lib/view.php:334 when calling
ensure_record_exists('view_rows_columns', $vrc, $vrc);. As the $vrc
record is created, the DB insert fails because $vrc->view is null, as
the view is not (yet) created.

The attached patch fixes this by ensuring the view is saved in the DB
(and thus haves an ID) before attempting to create the $vrc object.

Mahara version : 17.04.2
OS : GNU/Linux Debian 8.8
DB : MySQL 5.5
PHP : 5.6
