Set invoice method and payment term from last purchases
Just like we set the currency using the last purchases from the same supplier, we should also set the invoice method and payment term.
So this leads to the suppression of the supplier_payment_term
on party as it will no more be useful but I do not think we should implement the same behavior on supplier invoice because when they are created this way, the accountant has the invoice.
With such removal, the default of payment term (when unique) has no more sense. Instead we should have a default configuration for the customer payment term.
