Bug 37838: Fix broken remove button in course reserves

To test:
1) Go to staff client -> Course reserves
2) Create a course or go to an existing course
3) Add reserves to the course (will need at least 21 items to be able to go to a second page of results)
4) Go to the second page of results on the course details page
5) Click the Remove button next to a result
6) Notice how the button just makes the page move to the top
7) Apply patch
8) Repeat steps 1-5
9) Notice how the remove button is working as expected
