Motivation

This PR wouldfix#8928 and#8924. We had an issue with parsing the WSGI environRAW_URI, because an HTTP request can also contain a full URL and not only an absolute path. See the RFC:https://www.ietf.org/rfc/rfc2616.txt

   To allow for transition to absoluteURIs in all requests in future   versions of HTTP, all HTTP/1.1 servers MUST accept the absoluteURI   form in requests, even though HTTP/1.1 clients will only generate   them in requests to proxies.

We would then have more than the path withget_raw_path, which lead to issue down the road when trying to match in our router.

Changes

We now thanks to@dfangl parse theRAW_URI variable withurllib.parse.urlparse to then only get thepath part of theRAW_URI in case there's more.
Added a unit test covering this use case.
