Title: Fix/vik/studio oe

Fix several issues with open ended assessment.

* Remove incorrect/correct message to students, and rely on the rubric for feedback.
* Have markdown in studio by default, so that clicking save does not cause an error.
* Remove locations from staff grading view if the original problem has been deleted.
