Title: INT-2610 Gateway method mapping

fixed GatewayMethodInboundMessageMapper to ensure that:
- it looks at the Map key type and does not attempt to map Maps that have keys other than String to MessageHeaders
- does not attempt to map Map to a payload if payoad has already been set via expression
