[IMP] point_of_sale: Warning no chart of account

Point of sale config have multiple fields that depends on the accounting
localisation, but when you create a new company, the default values for
the journals, accounts, etc are not yet created because there is no
chart of account installed for the company.

So to avoid user that create a pos config to manually create accounting
journals and accounts, we are warning them to install first an
accounting localisation that will create them all necessaries account
and journals.
