Genesis SanityCheck Addresses once existing deployments have cleaned up registry

[ptrus]

Since existing deployments currently include invalid P2P.IDs and addresses we cannot yet sanity check those fields in genesis as it would prevent doing a import/export deployment. After next deployment, check if registry state is ok and can be sanity checked.

Validate P2P.ID and Consensus/Committee/P2P addresses after existing deployments have cleared up registry.

While here, we should also deduplicate the node descriptor checks, possibly by having the registry doc's SanityCheck call VerifyRegisterNodeArgs.
