"Group movies into collections" cannot be disabled

[BoboceaOctavian]

Describe the bug
If there are movies grouped into collections, Jellycon will always display them as a single item in the movies library, even if "Group movies into collections" is set to false.

To Reproduce

1. Add at least two movies into the same collection.
2. Open the movies library in Jellycon.
3. Check that the movies are displayed in a single collection item that can be opened to list the movies.
4. Go into the Jellycon settings, in the Interface tab, Item layout section and set "Group movies into collections" to false. Save and restart.
5. Open again the movies library in Jellycon.
6. Check that the movies are still displayed in a single collection item and not as separate entries.

Expected behavior
If the setting "Group movies into collections" is disabled, movies belonging to collections should be shown as their own entries in the libraries displayed by Jellycon.

System (please complete the following information):

• OS: Android TV 11
• Jellyfin Version: 10.8.13
• Kodi Version: 21.0-RC1
• Addon Version: 0.8.0+py3

Additional context
Collections have been created automatically with the TMDb Box Sets plugin.

I have disabled the setting with the same name in the Jellyfin server (Libraries - Display - Group movies into collections) and the "Automatically add to collection" setting for my movies library and also refreshed it. After this both the Jellyfin web UI and the Jellyfin Android app show the movies as specific entries in the library and the collections appear only in their specific "Collections" library.
