Hide inactive teachers from Courses view

    Currently, when you go to Admin > Courses, the 'Teacher' column will list all teachers, even if their enrollment is inactive. I'm not sure what benefit there is to seeing inactive teacher enrollments in this view, so I think it would be better to exclude that by default as it only seems to cause confusion.
