Fix bug in AuthMailer test that made it fail only half of the time
Fixed order dependant bug in auth_mailer_test

This was a tough one, let is lazy in Minitest, so it only actually sent
the email if the email-variable is used - which it is in most of the
tests, but in one I directly checked ActionMailer::Base.deliveries
before using email, hence that test failed whenever it was run first.
