warning needed when sending message to non-contact but have 'do not receive messages from non-contacts' setting on.

For this test you'll need two users, user A and user B. 1) User A should have 'Prevent non-contacts from messaging me' ticked in their messaging preferences. 2) Go to user A's messages. 3) If user B is a contact just click on their name to display their message history. If user B is not a contact, search for them and add them as a contact. 4) There should be no warning above the new message box. 5) Remove user B as a contact. 6) You should now get a warning above the new message box telling you that the other user will not be able to reply. 7) Log in as user B. 8) View the message history with user A. 9) You should get a warning saying that you cannot message user A and no new message box.
