HTTPretty: update to 0.7.1

The 0.7.1 release has a fix for the parse_querystring function, which raised a
TypeError on Python 3.3. See:

https://github.com/gabrielfalcao/HTTPretty/commit/5c6e77615f4083b9daf4a0148349f3185dcaff05

This helps fix some tests on Python3.3.

Move redirect handling to session

Particularly 305 is expected to be handled by the tests so we need to
handle this centrally if we want to have session and non-session clients
to work the same way.
