INT-4362: MMIH Catch Conversion Exception

Browse Source 
JIRA: https://jira.spring.io/browse/INT-4362

INT-4312 added a JSON conversion when there is a single method with a non-String parameter.

Add more tests for parameters of type `Message`.

Catch conversion exceptions and use the message as-is if the conversion fails.
