bugfix: schemas/vegbien.sql: taxonlabel_update_ancestors_on_{insert,update}(): only use either the matched taxon's ancestors or the parent's ancestors, to avoid issues related to duplication between these two ancestors lists. this also fixes a bug where the 2nd taxonlabel_update_ancestors() call assumes that the existing ancestors are for the old parent, when in fact they have actually just been set to those for the new matched taxon (which horribly confuses taxonlabel_update_ancestors()).
