CLONE - Students receive notification when their assignment submission is graded

This test requires an assignment with a student submission. The student should have popup notification and email checked for assignment submissions in their messaging settings.

1. Login as a teacher and access the assignment.
2. Follow the 'View x submitted assignments' link and click the Grade link for the student.
3. Add a grade and feedback and tick the send notification checkbox.

For the student to receive notification, you need to first wait for the maximum editing time (usually 30 minutes) to expire and then run the cron. (The wait is so that the teacher can edit the feedback without a notification being sent, similar to forum post editing and forum notifications.)

4. Run the cron by browsing to yourmoodlesite.org/admin/cron.php e.g. http://qa.moodle.net/admin/cron.php
5. Login as the student and check that they receive a popup notification that their assignment submission has been graded.
6. Check that the student also receives email notification.
