Bug 16939: (follow-up) Correction for orderreceive.tt

This patch makes a change to orderreceive.tt which corresponds to the
changes made in the previous patch.

To test, apply the patch and set the AcqCreateItem system preference to
"receiving an order."

- Go to Acquisitions -> Vendor -> Receive shipment.
- Submit the "Receive a new shipment" form.
- Click "Receive" for an order line.
- Fill out the item form and click "Add item."
- The table of existing items should display correctly, with a single
  "Actions" column containing an "Edit" and "Delete" button.
