Fix the py27dj19 tests

- Wrap the expected_url variable in a django 1.9 condition so that it
  returns as expected.
- Use request.GET/request.POST instead of request.REQUEST
- Remove some conditional code required for old Django versions

This is the first step in getting Horizon to fully support Django 1.9.
It does *not* yet aim to offer full support, which is why the
requirements have not been bumped.
