[FIX] l10n_nl: add 3bl tag on previous 3b affected lines

A previous commit made to add a new (triangular) tax introduced
a bug where the tag 3b (omzet) was archived, leading to journal items
not being picked up by the modified tax report.
This commit should add the new tag 3bl (omzet) on the items containing
the previous 3b (omzet) tag when upgrading the module.
