[FIX] contract: Don't execute onchange after invoice creation + Tests with duplicated name

- Don't execute onchange after invoice creation
  Using that approach (that is the current one in core)  has a lot of side effects and
  performance bottlenecks. You can read odoo/odoo#40156 for summarizing them.
  This also improves the handling of the values of payment term an fiscal position
  for using the partner ones if not set.
- Tests with duplicated name
  So they are not executed at all. Detected by chance looking for a test for the other PR.
