Support L2 Safes upgraded from non L2 Safes

Background

• When a non L2 Safe is replayed in a L2 network, indexer cannot pick it as setup event and initial state of the Safe is missed.
• We should find a way to support that kind of Safes in the UI.

Related issues

• Implementing contract for version migration: Add contract to migrate a Safe from not L2 to L2 safe-smart-account#685
• Implementing command on safe-cli: Add migration upgrade from non L2 Safes to L2 Safes  safe-cli#285
