[IMP] sale: Change default invoicing policy

Purpose
=======
The default invoicing policy should be based on the delivered quantities
by default because:
- In countries with anglosaxon accounting, that's mandatory
- Even for other countries, it's probably as frequent as the "based on ordered"
  quantities
