Describe the Bug

At startup Flatpak migrates an existing ~/.config/sunshine folder to /.var/app/dev.lizardbyte.sunshine/config/sunshine but it neglects to update the file paths for the game cover images in apps.json.
All game cover images are missing after the migration.

Expected Behavior

Sunshine either leaves the config files at their original location in ~./config or it takes care to adapt the relevant file paths in apps.json while migrating. Better yet: for images stored in sunshine's config folder, it should probably use relative paths instead of absolute paths.

Users should not put images inside the config directory...

[gschintgen]

Ah, right, I could have added that all cover images were saved at their default location by Sunshine's built-in cover search functionality. No image file was provided manually, neither did I edit apps.json manually.
