schemas/vegbien.sql: unscrubbed_taxondetermination_view: Sort by taxondetermination.taxonoccurrence_id instead of taxondetermination_id to allow scanning the taxondetermination_single_current_determination index, which includes only current determinations and avoids needing to scan past many non-current determinations. Note that using taxonoccurrence_id does not create sort order ambiguity between taxondeterminations with the same taxonoccurrence_id, because there is only one current determination per taxonoccurrence.
