Bug 11003: fix JS error on the staff cart page

A call to yuiToolbar breaks JavaScript code on the cart page.

Test plan:
- add some biblio to your cart
- open the cart
- a js error occurs (see it with firebug):
  ReferenceError: yuiToolbar is not defined
- apply the patch
- retry and verify the error does not appear anymore.
