DefaultMessageCollection getPayloadAsBytes() and getPayloadAsString(enc) throw UnsupportedOperationException

The issue of having these 2 methods throw an UOE is that they are called by Mule itself, like in DefaultMuleEvent.getMessageAsString(enc).

I don't think it is a correct behavior for Mule to trip on its own UOEs.
