Bug 21659: Fix links to basket groups from order receive page

Fixes a problem with the template variables on the order
receive page, so that the links to basket groups work
correctly again.

To test:
- Create some orders with and without basket groups
- Receive shipment
- Verify that the basket group links for pending orders work right
- Receive an order line
- Verify that the basket group links for received orders work right
