Bug 10317: improve display when order receiving page is given an invalid invoiceid

This patch fixes some things on the order receiving/parcel page.

1/ Removes dead code
2/ Displays an error message if invoiceid is unset or does not refer to an
invoice
3/ Fixes a bug in the note ("change note" and "add note" links)

Test plan:
1/ Try to call the invoice page with an existing invoiceid and check
that order results are consistent.
2/ Try without invoiceid or a bad invoiceid and check that an error
message is displayed.
3/ Add and change notes.

Works nicely for all tests done.
- parcel.pl with invalid invoicenumber gives a nice error message
- parcel.pl with a valid invoicenumber looks normal
- changing and editing order notes works well

Passes QA script.
