Expand description

Of the given exercises, the ones with at least one existing submission from any user.

Used to warn a teacher before saving a page edit that would drop one of these exercises: the exercise gets soft-deleted by exercises::delete_exercises_by_page_id, which orphans the submissions behind the deleted_at filter instead of removing them (course-improvements-issues#146).
