fix: pass pytest cms ProctoringExamSettingsGetTests

[Carlos-Muniz]

As part of #36, several tests have been discovered that are not passing in tutor, but passing in devstack. The following tests may not be run by tutor, or may be failing in tutor.

cms/djangoapps/contentstore/rest_api/v1/tests/test_views.py::ProctoringExamSettingsGetTests::

• test_providers_with_disabled_lti
• test_providers_with_enabled_lti
• test_200_for_lti_provider
• test_400_for_disabled_lti

For more information about the tests that passed, failed, skipped, or never ran, see the spreadsheet with all the tests.

Tests ran in lms bash via tutor dev run lms bash all pass.

This is not the case when ran in cms bash via tutor dev run cms bash.
This is because settings.ROOT_URLCONF = lms.urls, even when ran in cms bash.
This is related to https://github.com/overhangio/2u-tutor-adoption/issues/48

Closing this ticket because it is no longer needed and is a symptom of an issue documented in another ticket.

This test does pass in tutor. See #155 for more details.
