Bug 17631: Koha::Biblio - Remove GetHolds

C4::Biblio::GetHolds can be replaced with Koha::Biblio->holds->count

Test plan:
Create an order and place a hold on the biblio you have ordered.
On the basket view, you should not be able to Cancel the order and/or
delete the record
Receive the order, on the parcel page you should get the same behavior.
