• Closes fix: serviceName and portName must correspond to port binding #1226

This PR supersedes PR #1226 (by @paulish). For now simply sync'ing it with master. Unsure yet what type of test it would have... It seems covered? But I don't have a concrete example in mind.

Will have a look in this one later. It is in my backlog.

fyi: I am working on a test for this one when have time, but due to other issues in this project this is not a first priority.

Was looking into this past week. Still not sure I understand the problem because I managed to create a WSDL file that breaks it.
Basically, when there are two services and port bindings are in order of appearance it works, but once I change, for example, port order it breaks parsing. I assume this is what this PR was about. But it does not work, moreover it works same way before the fix.

Anyway, I continue investigating this. At least I have a good WSDL and a template for a test.
