Bug 10152: Default sorting wrong in parcels.pl

Bug 10152: Default sorting wrong in parcels.pl

When you are receiving an order, the list of existing invoices should
appear in reverse chronological order. Unfortunately, right now it
appears in regular chronological order.

To test:
1) Make sure you have multiple invoices that have varying shipment
   dates for a vendor. We will assume this vendor is called "Example
   Vendor."
2) Choose the "Receive shipments" button on the Example Vendor page.
3) Note that the invoices are sorted by regular chronological order.
4) Apply patch.
5) Refresh "Receive shipment" page. Note that invoices are now sorted
   in reverse chronological order.
6) Sign off.
