Use requests.compat.json instead of plain json.

The `requests` package kindly manages 2/3 compat for json for us, might
as well be consistent and use the same tool!

As a side note, I’d like to move away from `six` and depend directly on
`requests.compat`. I believe it has everything we need and then we can
ditch the `six` dep and know that we’re always in sync with whatever
requests is doing (which is really what we care about).
