[Triage] Output Path Template {{ playlist }} is always "NA"

[csammis]

Describe the bug
When using a Media Source output path template that includes the key {{ playlist }}, the literal string "NA" is produced instead

To Reproduce
Steps to reproduce the behavior:

1. Create a Media Profile
2. Ensure the Output Path Template includes the key {{ playlist }} - for example, /{{ channel }}/{{ playlist_title }}/{{ upload_yyyy_mm_dd }} - {{ title }}.{{ ext }}
3. Set all other required options and save it
4. Use the Media Profile for a new Source that is specifically a YT playlist, for example https://www.youtube.com/playlist?list=PLZioPDnFPNsGnUXuZScwn6Ackf6LGILCa
5. Downloaded media is saved to /{{ channel }}/NA/{{ upload_yyyy_mm_dd }} - {{ title }}.{{ ext }}
   Expected behavior
   The output path template component should be saved with the playlist title or ID as described in the yt-dlp documentation.

Additional context

The predicted_media_filepath for a pending item does in fact have the correct value substituted for {{ playlist }} so this seems to be working on some level, perhaps just not when the files are actually written to disk
