We want to invigorate a Tax Name Taxonomy so that tax names are as codified as possible. This allow for a better display on Invoice Description, and allowed us to implement a smart name_search. During the previous pr to modify the taxonomy, some taxes (with same tax type) had the same name, which is obviously wrong. Now every name is unique. closes odoo/odoo#121126 Task-id: 3052677 Signed-off-by: John Laterre (jol) <jol@odoo.com>
