api: Fix running with requests 1.0.x.

Browse source 
I would prefer to be testing the attribute itself rather than the
version, but it's not easy to access without an actual request object,
and I'd prefer to compute this once-and-for-all on startup, rather
than on each request, since the latter just seems fragile.
