Travis test failing

Thanks for this good package.
However, the Travis builds are currently failing. Can we fix this?
Thanks.

I've looked further into this, and it seems there's a test case where we're reasonably passing in an empty SoapClient and expecting an error. However, a function call further up the request stack dereferences a pointer to Client.Definitions, which shouldn't even exist in the first place (since the SoapClient is empty).
