Remove logic for restoring legacy JSON backups

Browse Source 
- Protobuf backups have been around for 1.5 years now
- The ability to restore online-dependant data from JSON backups gets harder as time goes on and sources drift
- If users really need a way to restore them, they can use an older version of the app, or a separate tool for translating between the formats could be created
