Fix Retry Mechanism

[scouech]

When the an error is thrown during initialisation, the app tries to retry but an error occurs.

To reproduce this, throw an error in appInitializationProvider (e.g. alter the INIT_TOKEN and rerun the app)

Unhandled Exception: 'package:riverpod/src/framework/element.dart': Failed assertion: line 476 pos 11: '_debugCurrentlyBuildingElement == null || _debugCurrentlyBuildingElement == this': Providers are not allowed to modify other providers during their initialization.

Please also write unit tests to test these scenarios.
