Task 2297165
Set the payment reference standard to the one of the country of the
company by default.
The module l10n_be_invoice_bba has been merged into l10n_be as it was
auto_installed, it will not be problematic not being able to uninstall
it, and the order of installation of modules made it so that the
journals were created before l10n_be_invoice_bba was installed. This
caused the value to be set to 'odoo' on a fresh database instead of 'be'
