Unhandled error evaluating nonexistent response message

[tomesla]

If you use the step to evaluate a respond message of a Endpoint, but that Endpoint dont respond with a message in his body.
Wakamiti fails the evaluation and show an ERROR execution in the test and not a FAILED test.

It would be great, if Wakamiti can control this case to mark the test as a FAIL, because the Endpoints can loss his message respond product of an development issue and that must be cheked.
