Bug 11141: retain pending order filters during receiving.

Bug 11141: retain pending order filters during receiving.

On receiving orders, the librarian has to filter again the pending
orders list.

This patch stores the filters in a cookie in order to apply them when
the librarian finish a receive and come back on the pending orders list.

Test plan:
1/ choose a vendor with several baskets and orders.
2/ start to receive an item.
3/ on the pending orders page, add some relevant filters.
4/ receive an item.
5/ you are back on the pending orders page and filters are directly
applied.

Passes all tests and QA script.
Tested with receiving and cancelling the receive process the
filters are kept.
