#1943 Cant Send in 4.2 and Return in 3.x
When a 3.X endpoint does a Bus.Return that targets a 4.2.0 endpoint the v4 endpoint can't process the message. This makes it wire incompatible.
repro https://github.com/Particular/BugsRepro/tree/master/1943MissingCompletionMessage
So in a 4.2 endpoint
Bus.Send("Returner", new Message())
.Register<int>(i => Debug.WriteLine(i));
