wsgi: pep8 fixes

I have to say it's the first time I see the H302 code and I use flake8 with a bunch of plugins enabled. @tsg- what pep8/flake8 plugins do you have installed?

I don't see any particular reason behind this rule and I think following it would only make code more cluttered with qualified references.
