[FIX] repair: use Customer Payment Terms in repair invoice

- Install Contacts and Repairs
- Go to Contacts and configure Payment Terms of Contact X (i.e. 2 Months)
- Go to Repairs and create a Repair Order:
  * Select Contact X as Customer
  * Select "Before Repair" as Invoice Method
  * Add Parts or Operations
- Confirm Repair and Create invoice
The Payment Terms of the created invoice is the default one and not the Payment Terms of Customer.
