[FIX] sale: do not take into account old invoices in sub renew

To Reproduce
============
- create a subscription
- confirm it and create invoice for it then confirm it too
- go back to the subscription and renew it
- from *Action* generate a payment link
- a validation error will be raised

Problem
=======
we can't generate the payment link because the amount is 0, this value came from the fact that we substract
the sum of invoices amount linked to this subscription from the total amount.

Solution
========
The invoices from the old subscription are kept just as history in the new one, and must not be taken into account when
computing the amount, so a condition was added to remove theses kind of invoices from computation of amount.
