Change ProtoNumber of Backup Models for History and Source to a non-zero digit (#5849)

* Change ProtoNumber of Backup Models for History and Source to non-zero

Changed BackupHistory url and BackupSource name properties

* Provide backwards compatibility to current proto backups

- Added data class for zero-based protoNumber
- Restore both 'new' proto and old ones by mapping old to 'new' proto format
- Thanks to @jobobby04  for providing the initial solution.

* Fix on createBackup missing parameter for brokenSource

* Fix issues on build

* Fix missing import on FullBackupRestore
