The default taxes for most localisations have been left undefined by
default. When loading the chart template, the model generally selects
the first sales and purchase taxes, based on the order in which the
taxes appear in the csv, for the default sales and purchase taxes
respectively.
This behaviour can be confusing to those who are not yet familiar with
it. It has been decided that it is preferable instead to specify the
default tax in _get_*_res_company function on the account chart template
model, such that the default taxes are defined explicitly for every
localisation.
