Bug 29658: Fix crash on cancelling cancelled order

Found this crash in our 20.11 logs:
Cannot insert order: Mandatory parameter biblionumber is missing at /usr/share/koha/acqui/cancelorder.pl line 60.
 at /usr/share/perl/5.28/Carp.pm line 289
        Carp::croak('Cannot insert order: Mandatory parameter biblionumber is missing') called at /usr/share/koha/Koha/Acquisition/Order.pm line 79
        Koha::Acquisition::Order::store('Koha::Acquisition::Order=HASH(0x55f3760e2860)') called at /usr/share/koha/Koha/Acquisition/Order.pm line 189
        Koha::Acquisition::Order::cancel('Koha::Acquisition::Order=HASH(0x55f3760e2860)', 'HASH(0x55f375a17ec0)') called at /usr/share/koha/acqui/cancelorder.pl line 60

Not sure how to reproduce this one as it happened. But might be related to repeated clicking, backspacing etc.

Test plan:
Create a new basket and order.
Open this same basket in two browser tabs.
Cancel the order line (delete catalog record) in tab 1.
Go to second tab, try again.
Without this patch, it will crash. With this patch, an error message.
