Improve validations run outputs through the CLI

When the tripleo.messaging.v1.send workflow fails with the error
'Workflow failed due to message status', the return message is None and
we don't have more information about what's failing. The same happens if
the validation runs well.

This patch improves the output in case of a messaging workflow failure.
