Error message from course slug collision does not explain the problem

[ragesoss]

What is happening?

Attempting to change a course slug component (such as title) will result in a server error if it changes the slug to match another course. However, the error message shown in the UI is just "Internal Server Error". It should instead explain the problem so that the user can choose a different string, or navigate to the other course and delete it (if it's not being used).
