INT-4541: Fix Reactive MessagingGateway Errors

Browse Source 
JIRA: https://jira.spring.io/browse/INT-4541

Add test case to reproduce.

The gateway correctly sets up the `errorChannel` header so that a downstream
`MPEH` will send exceptions back to the gateway, but the `map()` function
did not check for an error message.

Check for an error message and throw the payload so that the `onErrorResume`
will route to the error channel.
