The method already sends a custom post_save signal so to make it
consistent it now also sends a pre_save signal.

The initial check if the voucher is available was done before creating
the order. This change adds a validation step during the order creation
within an atomic() block.

See #2101

The try/except clause to check if an order exists seems a bit weird and
non performant here. Just use .exists()
