Cleanup: use the right context for CommitDescriptionController.Context()

It doesn't seem to be used by anything, it looks like we only need to implement
the method so that the IController interface is satisfied. But still, it doesn't
hurt to be correct here, and might avoid confusion in the future when somebody
does try to use the method.
