Fix disabling of location header autocorrect for werkzeug 2+

[AdamWill]

In werkzeug 2.0.0 and later, the Location header autocorrection moved from BaseResponse to Response, so we need to set autocorrect_location_header = False in Response not BaseResponse. For now let's just set it in both to be safe, this doesn't cause any errors at least with 1.0.1 and 2.0.1.

@kinlane This PR is a pre-requisite for getting the tests running again when we move them to GitHub Actions - see https://github.com/MikeRalphson/httpbin/actions/runs/1174257560

Closing in favor of #674 , as setting both isn't valid any more (plus this wasn't doing it entirely right).
