The aimf of this commit is to make the query of a specific tag with a specific sign easier by avoiding all the filtering in `expression._get_tax_tags().filtered(lambda t: t.tax_negate)` With this commit, we just leverage the existing filtering on domain to only get the desired tag. no-task closes odoo/odoo#117167 X-original-commit: 6eb53a3802d24e283b8334b6f245ffe87dddcbe8 Related: odoo/enterprise#39044 Signed-off-by: Olivier Colson (oco) <oco@odoo.com> Signed-off-by: Brice Bartoletti (bib) <bib@odoo.com>
