test: Remove reference to the courseware url.

The courseware URL is going away but it's just used here to test the
middleware.  That can be test with other urls that are relevant to this
middleware.

Note, I was unable to re-produce the failures so I've put back using the
standard `reverse` logic for fetching the URL in the test.
