Users still receive notifications for messages, even if they disable notifications for messages.

Steps to reproduce:

1. Go to View All notifcations as User 1 and disable recieving notifications for private messages
2. Send a message from User 2 to User 1 (via contacts center, or the messages dashboard).
3. Assert that User 1 still receives a notification for the message, even though they have disabled notifications for messages.

Expected results:
After disabling notifications for private messages, a user should not be notified the next time they are messaged.

Actual results:
User still receives notifications for messages, even if they disable notifications for messages.

Note that at the time of testing, each of the other notification types could be disabled as expected. (tasks, contact request, etc). Private message was the only one that was not working as expected.
