ReplyProducingMessageHandlerWrapper does not have it's onInit method called

Spring Integration version 5.0.8 (I suspect because of INT-4518) causes ReplyProducingMessageHandlerWrapper to not be initialised.

In 5.0.7 - ReplyProducingMessageHandlerWrapper the code which calculates the handlerExists returns false and thus the ReplyProducingMessageHandlerWrapper is initailised.

However switching to 5.0.8 the handlerExists calculates to true and thus the onInit() method is never run and my advice is thus never applied...

See postProcess() method org.springframework.integration.config.annotation.AbstractMethodAnnotationPostProcessor

INT-4518 modified the code that calculates the handlerExists it seems to have affected the behavior when a ReplyProducingMessageHandlerWrapper is used.

I'll try and get time to create a test project...
