[FIX] l10n_id_efaktur: payment terms blocking payment
Setup indonesian invoicing
Create a payment term with payment in 30 days and 10% if paid before 2
days
Create an invoice with said payment term
Confirm and register payment
Operation will be blocked by error
"Cannot mix VAT subject and Non-VAT subject items in the same invoice
with this kode transaksi"
This occurs when creating the payment move. All the lines have
display_type set to 'product' (defualt value), so the system checks
consistency of kode transaksi as in an invoice
