[FIX] payment_stripe: always create a customer for one-shot payments

Following commit ac90aa07, the Customer object was no longer created on
Stripe for one-shot (non-recurring) payments made with Stripe. This
prevented Radar (Stripe's fraud detection tool) to work effectively as
it could not rely on the customer's name and addresses anymore (see
https://docs.stripe.com/radar/integration#recommendations).

This commit forces the creation of a Customer object even for one-shot
payments.
