Strip query string before testing which urls to strip cookies on

[instification]

This is a PR to resolve issue #42

Instead of comparing the url to req.url compare it to a new variable set on req.http which has the query string removed.

LGTM. Just for some reason at the coverage report on Travis is hanging, I restarted the job.

thanks for looking at that @jensens

what is the procedure now you have approved it? Do I just merge the PR or should I wait for a package maintainer to do it?

I've submitted another pr #44 to try and address the issue with travis
