sale_financial_risk: partner_invoice_id issue

[abirbasolt]

The partner_Invoice_id is who is going to pay, so would be more logical to check the credit from the Partner_invoice_id when you confirm the order.

I told you about opening 2 separate issues. Let's keep this one for the first, so I edited the original text.

@carlosdauden what do you think about this? I think it can be logical to put the risk on the invoicing partner, not the ordering one.

[carlosdauden]

I agree

[pedrobaeza]

@abirbasolt you can open then a PR solving the problem.
