Bug 11699: fixed saving notes entered when receiving orders

Revised test plan:
1/ Create an order with 2 items
2/ Receive 1 item and enter a note for the order
3/ Verify the note is not saved
    The note should be visible on the Mod Order Details screen,
    but it isn't there.
4/ Apply patch
5/ Receive the second item and enter a note for the order
6/ Verify the note is correctly saved
    The note is visible on the Mod Order Details screen.

Passes all tests and QA script.
Works as described. The note now saves correctly and also remains when
you undo a receipt.

Note: it would be nice to show the note on the receive page as well.
