Bug 41420: Fix referrer in parcel.tt

Test plan:

Steps to reproduce :
1 - Go to http://localhost:8081/cgi-bin/koha/acqui/neworderempty.pl?booksellerid=1&basketno=1 and fill in a new item.
2 - Visit http://localhost:8081/cgi-bin/koha/acqui/parcels.pl?booksellerid=1, type an invoice name and validate. Inspect both "Cancel order" and "Cancel order and catalog record". Notice the link in "Cancel order is broken"
3 - Apply patch
4 - Repeat 3 and notice the referrer is well formed.

For a reason I ignore, it does not seem to have an impact on main, but
on the 24.11 I tested, if you click on cancel order, after confirming
the deletion and clicking on "ok", you will be asked again to confirm,
    however the deletion has been performed
