db/simple: add missing "return"

SimpleDatabase::Visit() always throws exception when visiting a song. Adding a song to the queue always results in a "No such directory" error response, although the song is successfully added. This behaviour was introduced by commit 3ff728ab. This patch fixes this. https://bugs.musicpd.org/view.php?id=4601
