[IMP] point_of_sale: pos journal for each company

When the accounting localisation is installed after the POS config, the
values on the default POS config which is in data are not completed
because the POS config has been created before any journal exists.

So now, when a chart template is installed, we are completing the POS
config values, and creating the Sale POS journal. We also call the
creation of POS journal when the point_of_sale module is installed after
the template is installed on the database to be sure that we have a
default value for POS journal.
