Title: Force MessageRepository#exists? to use result of scope.exists?

Without this test it would be sufficient for MessageRepository#exists? to always return true.

I'm not necessarily saying we should do this, but I am interested in understanding more about when we should write tests that force more than just a dumb implementation and when we don't need to bother.
