Search both TFR synonyms and unaccepted scientific names for taxon matches

Right now when someone tries to type in a taxon name, it will match on unaccepted scientific names (the names with strikethrough in the name list on the taxon page). However, sometimes there are additional synonyms listed in the taxon framework relationship. I would like to see the taxon search look for matches in the TFR before attempting a name import from external name providers.
