[Courses] Remove long name/short name distinction for courses when they are the same

[KyraK]

When the course code is identical to the course name, would it be possible to just use one course name, instead of distinguishing between long name and short name (i.e. course code)? Having this distinction leads to confusion, as the course code is not visible in the list of courses in the "Courses" menu, and neither in the Inbox. On the other hand, when using the same name for the course name and the course code, this appears twice on the Dashboard, which is superfluous.
