[FIX] delivery: avoid tests to fail with l10n_*

The problem is that the cache still thinks in the test that
it is in EUR and then it does a currency conversion for calculating the
delivery cost and the test will fail in L105 of test_delivery_stock.py

By invalidating the cache after the sql that change the currency of the
company, we solve it.
(someone should refactor those tests though)

closes odoo/odoo#67790
