Increase test coverage

[Nathan-Nesbitt]

The following is similar to the current test coverage for the library:

----------- coverage: platform linux, python 3.9.7-final-0 -----------

TOTAL                             425     42    90%

I think it might be useful to write some more tests for the following sections? As it is a little tricky to tell if changes are impacting different parts of the library at the moment.

• spylib/oauth/redirects.py
• spylib/oauth/router.py
• spylib/token.py

Especially the OAuth section, as the current tests are only testing a single run-through of the OAuth process and doesn't check erroneous cases and how they are handled.

I'd suggest to do some clean up first. I believe some stuff related to jwtoken.py needs to go, if not all of it. That's another way to increase code coverage: get rid of code that's not tested ... and not useful! 😉
