[16.0] partner_duns: DeprecationWarning when running tests

[bouktaibMohssin]

Module

partner_duns

Describe the bug

The partner_duns module is using the deprecated SavepointCase class for tests, which has been merged into TransactionCase in Odoo 16.0. This causes a DeprecationWarning to appear when running tests.

To Reproduce

Affected versions:
Odoo 16.0

Steps to reproduce the behavior:

1. Run tests in the partner_duns module on Odoo 16.0 using OCA CI.
2. Observe the following deprecation warning:
   DeprecationWarning: Deprecated class SavepointCase has been merged into TransactionCase

Expected behavior
The test should not trigger any deprecation warnings and should use the current TransactionCase class.
