fix for incorrect property name

[denisoby]

Hello, everyone. Thank you for this module, I'm using it for my node JS project.

Recently I've got an error. My api contains url with zero as one of parts:

/api/0/someMethodName

And this causes error, because generated client contains code

this.0

This is correct url, but incorrect JS client code. So I suggest changing client template to safer property addressing through square brackets.

Thanks a lot. Not sure about the fix since it probably breaks some clients and would need a major release. I think at least.

Can you also add some tests, please?

@sichvoge I've change to example.raml - is enough. Without fix - generated JS is incorrect and will fail all tests.
