Facture not deleted on facturation.pro after a refund is processed

[markonikolic985]

Describe the bug

Some users asked fo rcredit note/refund invoice after we provider the refund, so I noticed it is not generated automatically in facturation.pro. This is something that should be done automatically after the refund is processed.

Latest example:

User: https://app.imagify.io/account/manage_users/[email protected]/
Facturation: https://www.facturation.pro/firms/28551/customers/1866331
Stripe: https://dashboard.stripe.com/customers/cus_HQtUXOnALtklcz

To Reproduce

1. Find refund request in HelpScout
2. Process the refund and cancel subscription
3. Go to facturation.prp and check if credit note is created

Expected behavior
You should see negative balance invoice like this
