My testing indicates that this change isn't working as intended. The message handler that gets scanned in UnicastBus.IfTypeIsMessageHandlerThenLoad() is the SagaMessageHandler, so it ends up subscribing to a message of type "System.Object". The IMessageHandler<> declarations on the Saga never seem to be scanned, so the bus is unable to auto-subscribe the saga to the messages.
