BUG: creating a classroom is not creating gradebooks

[pollygee]

When you create a classroom it should create quarters the school year.
We have bug that the quarters aren't getting created and therefore gradebooks aren't getting created.

We need to fix the bug and add tests to cover this behavior.

Didn't have a chance to get to this, I may reassign to myself tomorrow if no one has picked it up before then.
