 * generating the messages - basically, cloning that view and adding a join to the appropriate
 * message table. Those views may or may not be default views. In hook_views_default_views(), we
 * cannot load a default view without creating an infinite recursion. In
 * hook_views_default_views_alter(), the default views are present but not the others. So,
 * we use both hooks to catch all cases.
