[FIX] sale: set payment type to form

current expression implies that any payment of a quote from the portal (/my/quotes) will try to save a token whenever the user says they want the customer to pay online, which seems bizarre. Normally you'd only want that for quotes with subscription products, and there is an override of that method in sale_subscription for that specific case.
