Fixes issue where words are sorted by audio filenames if the first analysis writing system is an audio one.

Description

The default sort uses the first lexeme form (if no citation form is present) which is a problem if the first analysis writing system is an audio writing system. Then the entries are sorted by the filename, which results in a meaningless sort. This pr prevents '-audio' citation forms and lexeme forms from being used.
