Review namespace binding in server response

[w666]

Creating this issue for myself, but any feedback is very welcome.

Recently, I was working with Cytric cCDV API (owned by Amadeus) and they have pretty bad WSDL and request/response examples. While WSDL is valid and examples are not, I noticed that node-soap does not correctly use namespace prefix for some types. I can't publish WSDL here but will try to create simplified version that replicates the issue. Also, seems like SoapUI generates correct server response, that is different from provided examples.
