This means deleting the notifications for each message in the thread, for each
recipient on the thread. Previously, only a subset of these were being deleted.

This changeset removes a test that used a dummy thread_id, a testing
technique that doesn't work with the new looping technique used for
notification deletion. The new unit test is a proper replacement.

Props pareshradadiya for an initial patch.
