Steps to reproduce
============

1. create new assignment
2. set a scale as a grading method
3. do not grade any submission!
4. go to the grade book and see the assignment grades

What I expected
==========
The name of the scale should be displayed in the grade book.

What actually happened
===============
The assignment is considered as one with maximum grade "100" points. This leads to wrong final grade calculation because students never receive points in this assignment. That's why I set this as critical issue.
