Follow 302 redirects, don't mix quotes

[DeviaVir]

This change allows a WSDL and SOAP request to follow redirects returned from the servers (yes, I have to work with some freaky API's).

• Runs itself again to follow the redirect (replacing ':80' and ':443' to make sure the request will actually work)
• Replaces all double quotes by single quotes, since there was a mixed use

Hello @DeviaVir and sorry for the long delay - I'm really short on schedule in 2015 😞

Thanks a lot for your contribution, this seems like a viable addition to our library and we appreciate it a lot ! 👍

In order to get your PR merged, I'll have to ask you to add tests for your code change, as otherwise we can't easily identify and prevent regressions, etc. Please have a look at our Guidelines on Submitting a Pull Request, in advance 😃

Hi @herom, understandable! I'll take a look at your tests and will see if I can add one or two for this use case. Thanks for your feedback!

[DeviaVir]

@herom I found an even simpler way of accomplishing this:
https://github.com/vpulim/node-soap/pull/577/files#diff-1c0f1c434b17b7f8795d44a51a14320aR42

I ran your test suite and had 25 errors to start with, and didn't notice any tests that already do something with a stubbed server. Now that this change is down to a oneliner (if you ignore the replaced quotes and the added var), do you still require tests?

[DeviaVir]

@herom Actually, screw what I said. Will this test do? https://github.com/vpulim/node-soap/pull/577/files#diff-b55da8ee78a31a9a99b59b4cd544075dR265

@DeviaVir thanks a lot for keeping track and don't loose interest 👍
