Bug Description

When selecting certain video files, the default subtitle track selected by the jellyfin-roku is different from the default track used by jellyfin-media-player (v1.12.0).

Steps to Reproduce

1. Set up a Jellyfin server and a user account.
2. Open jellyfin-media-player, log in to that user account, and configure:

Settings -> Playback -> Preferred audio language = "Any language"
Settings -> Subtitles -> Preferred subtitle language = "Any language"
Settings -> Subtitles -> Subtitle mode = "Default"

3. Add an MKV video file to Jellyfin which has the following:
   • exactly one audio track, which has language: "jpn", enabled_track: true, default_track: true, forced_track: false
   • ecxactly one subtitle track, which has language: "eng", enabled_track: true, default_track: true, forced_track: false
4. Select this video file in jellyfin-media-player. Note that the subtitle track is selected to play by default.
5. Open jellyfin-roku and select the same track. Note that "None" is selected as the default subtitle track, which does not match the behaviour of jellyfin-media-player.

Expected Behavior

jellyfin-roku should select the subtitle track as the default playback option, instead of "None".
