Feedback view: Fix courses view

[numbleroot]

It is hard to parse the additional information given in module descriptions in MTS such as that only 6 ECTS have to be chosen out of the listed 12 ECTS. Therefore, the MTS descriptions is always to be considered the source of truth. But courses should still be handled correctly. @uhlo enhanced the module crawler to include additional identifiers so that identically named courses with different teaching forms (lecture vs. tutorial) should be able to be kept apart. Correct the feedback view to reflect these changes.
