After an upgrade, a migrated genesis files contains the root hash of the application's merkle tree, and an arbitrary bytestring which can be used to perform component-specific health checks. Although the field is a no-op in the simple upgrade scenario, it is a bit confusing that it contains
[32u8; 32]
instead of the application hash. This PR fixes this.
