Markus Heiser 77a0f33819 [fix] engine duden - don't raise exception on empty result list
Duden expects a word in German, so with query "amazing" the site finds nothing
and respons a 404:

    httpx.HTTPStatusError: Client error '404 Not Found' for url\
      'https://www.duden.de/suchen/dudenonline/amazing'
