fix multiple due dates from overlaping in modules
fix multiple due dates from overlaping in modules

fixes CNVS-12637

When you go to the modulese page if you had multiple due dates it would
overflow into the pts column. This no longer does this.

Test Plan
---------
As a teacher
Given I have multiple sections set up in a course
And I've added an assignment to the modules page
And that assignment has multiple due dates on it
And that assignment has points on it
When I go to the modules page
I should the module item with multiple due dates text
And it should not be overlaping the points column
