schemas/vegbien.sql: taxonconcept: taxonconcept_update_ancestors(): Use matched_concept_id's ancestors instead if available. (Recursively applied, this will use the ancestors of the accepted concept.) This facilitates finding all children of and matches to an accepted concept, which will all have an entry for that concept in taxonconcept_ancestor. Note that the concept's own parents will not be indexed in taxonconcept_ancestor, because only accepted ancestors are now stored in taxonconcept_ancestor. Documented that taxonconcept_ancestor now stores the accepted ancestors of a taxonconcept.
