We're using 'requests.PreparedRequest' in one place in the tests.
However, the requests docs have a warning that one shouldn't do this:
Instances are generated from a Request object, and should not be
instantiated manually; doing so may produce undesirable effects.
It seems we're now seeing just such an effect, as requests has started
attempting to do proxy-related things resulting in the following error:
Traceback (most recent call last):
File "/usr/lib64/python3.6/unittest/mock.py", line 1183, in patched

if 'Proxy-Authorization' in headers:
TypeError: argument of type 'NoneType' is not iterable
Do what we should have done from the beginning and use
'requests.Request.prepare' instead.
