Bug 36018: biblio->active_orders should be ->uncancelled_orders

Active orders are more than just not cancelled. See filter_by_active
in Koha::Acquisition::Orders. They are still in the acq process; we
still need to receive items on those orders.

When we cancel and want to delete a biblio, we should check for not
cancelled orders (broader than active orders as in Orders.pm).

Test plan:
Git grep active_orders.
Run t/db_dependent/Koha/Biblio.t
Run t/db_dependent/Koha/Acquisition/Order.t
Add two order lines in a basket referring to same biblio. Try to
cancel with delete biblio. Should not be possible.
