Patch from @JSaleh about several modifications to the test framework so that it interacts properly with the api and students are able to run tests made public by the instructor.

Description follows:
Modified aspects of the test framework to fix issues such as proper response to API request and students are now able to run and view tests.

Ran both Unit and functional tests, Manual testing to ensure results were being properly stored.

Patch can be found here:
https://gist.github.com/4055194

We need to integrate this patch to MarkUs' source code.

@benjaminvialle In #1002, you mentioned that the API will mostly be used by admins/TAs. The suggested changes in that gist (diff is outdated now) would have allowed students to upload their own test results to the framework via the API. But I don't think exposing a single route to students would be worth it. Think we can close this?
