[Bug] Issue with "Favorites" and "Playlists" folders in :latest docker image

[byteonabeach]

Description

In the latest version (latest tag for the container) of the server build, there's a bug-like behavior with the "Favorites" and "Playlists" pseudo-folders in the Folders section.

Steps to Reproduce

1. Enable the feature for pseudo-folders without assigning a root directory yet (or just setting it $home).
2. Observe that the Folders section displays these two pseudo-folders.
3. Via the Web UI, connect a root directory (e.g., mapping /some/long/real/path:/music).
4. Check the Folders tab after connecting.

Expected Behavior

• The root directory should be added as a list of its subfolders (e.g., subdirectories under /music).
• The pseudo-folders "Favorites" and "Playlists" should remain visible alongside the real folders.

Actual Behavior

• The root directory is added as /music itself (not expanding to subfolders).
• The pseudo-folders "Favorites" and "Playlists" disappear from the Folders section.

Additional Investigation

I inspected inside the container and checked the JSON config file. The values update correctly there, so the issue doesn't seem related to config persistence.

Additionally, if you save the config created from scratch in the latest container and then run :v2.0.9 with this same configuration, everything starts working perfectly.

Sorry guys, I can’t read what you committed there, I just want to report the problem. All would be swing!
