Tests for pm_email_notifiy.module

Hey Berdir,

With the pm_email_notify sub-module enabled, there is a fatal error (White Screen of Death) after clicking "Send Message."

Here's what it said in my Apache logs:

PHP Fatal error: Cannot use object of type stdClass as array in /Users/benkaplan/git/drupal/modules/user/user.module on line 2613
