Describe the bug
Project Options -> Subtitles -> Demux preferred languages but don't include them

• this setting does not demux the preferred langauges (= create the subtitle files in the temp folder) anymore since 2.42.0

Expected behavior
Demuxing should work the same as in 2.41.x

How to reproduce the issue
Activate Project Options -> Subtitles -> Demux preferred languages but don't include them
Open a file that includes subtitles of the preferred languages

Provide information
The temp folder for the file does not include any subtitle files. First I thought this was related to some kind of bad import of settings (which I didn't actually do really), but I when I made sure and recreated all relevant settings from complete scracth with 2.42.0 the issue remained.
