Subject: Attempt to fallback on kanji or terms dict when no results are found
 in the other (#1141)

* Attempt to fallback on kanji or terms dict when no results are found in the other

* Move logic to _findDictionaryEntries and split out _getFindDetails

* Fix not falling back both ways properly

* Add source to findDetails

* Simplify return

* Search fallback kanji without wildcard

* Avoid double searching kanji

* Remove weird newline

* make symmetric

* Simplify flow
