[FIX] point_of_sale: make test work with localisation modules

When localisation modules such as l10n_no are installed, the test
TestAngloSaxonCommon broke.
We isolate the test more by setting the right accounts on the products to make
the test pass.
This is useful for odoo.sh clients that install localisation modules and see the
tests break.
