tests: Setup environment variables and configs

* gn3/settings.py: leave `OAUTH2_ACCESS_TOKEN_GENERATOR` in its default
  setting
* tests/unit/auth/fixtures/oauth2_client_fixtures.py: setup
  `AUTHLIB_INSECURE_TRANSPORT` before running the OAuth2 tests
* tests/unit/conftest.py: setup the test application's configuration correctly
  for the tests.
