Syncing wipes/edits favorites.txt

[thisiskyle]

Describe the bug

If files on the flipper are sorted into subfolders beyond the root application folder (example: /ext/subghz/sub_folder/file.sub) and are also in favorites.txt, are removed from favorites.txt after syncing with the android app.

Files that are not in subfolders (example: /ext/subghz/file.sub) act as expected and remain in favorites.txt

Possibly related to issue #284

To Reproduce

1. Place a file on the flipper in a subfolder such as /ext/nfc/my_folder/file.nfc
2. On flipper, pin the file to your favorites
3. Connect flipper to android app via bluetooth
4. Sync device and app
5. Check favorites.txt

Expected behavior
Pinned/Favorite files should remain in favorites.txt after syncing with android app
