Student tests using incorrect url

[brianjbeach]

If I understand the intent of these tests, you should be sending the request to /initial_student? rather than /initial_unknown?. Also, in the first of the two tests you are passing a role of "Staff". Staff is the name used in the decorator, but you should be passing either Administrator or Instructor in the in the request.

	consumers, url, roles='Staff'
