[FIX] account_check_printing: wizard use vendor payment method

The payment method added by account_check_printing is meant as:

> Preferred payment method when paying this vendor. This is used to
> filter vendor bills by preferred payment method to register payments
> in mass. Use cases: create bank files for batch wires, check runs.

But it may also select the default payment method on an account.payment.

With this changeset, we copy what is done in account.payment to
account.payment.register so the behavior is the same for it.
