Updating backup restore logic

> Adding DeviceProfile information in the backup
> Removing SharedPreference backup
> Adding helper methods to abort backup in the middle
> Comparing keys against the backup journal during restore
to avoid restoring corrupt/lost entries
> Old backups are still compatible, but lost keys verification
will be ignored in that case.
