Fix two bugs:
1. &modify_single_student did not expire old student roles in the course.
This has been implemented by calling &londropadd::modifystudent.
2. &modify_single_student handled the 'override student id change' stuff
improperly. Now a check is made to determine the the student has an
id before bitching about attempts to change the users id.
