Due to the relationship between fiscal position
templates and tax templates, the removal of
obsolete tax templates may crash if the corresponding
fiscal positions are not deleted before.
In a recent l10n_fr patch [1] a number of
templates disappeared, which causes an error during
subsequent updates on databases where the obsolete
templates are still present.
As a workaround, we can force a deletion of
all fiscal position templates before loading
them. This is relatively safe because the templates
are not connected to live data, and will be
re-created during the update (except for the
obsolete ones which will be gone forever).
