Add consistency test for updating taxon names

[ehwenk]

• add a consistency test to show that the step in create_taxonomic_update_lookup() that updates the aligned names currently works
• currently breaks for genus-level alignments and names from the APNI list
• eventually need to expand the test to also include other columns
