Lazy creation of public keys from AccountId in the
GenesisStorageBuilder::build()method.Reason: the new strategy better fits when we require to create keys using a different scheme.
Previous approach assumes that all the runtime pallets will require the same scheme (sr25519) but this is not always the case (sassafras uses bandersnatch vrf keys or grandpa).
Postponing the creation of the keys allows to maintain only the account ids list in the builder and then create all the key types we require (currently only sr25519) when we require them
Other trivial tweaks:
substrate-test-pallet'sAuthoritiesstorage is used to store other protocols keys that doesn't instance the pallet within the test runtime (e.g. aura). Thus, is more appropriate to store a raw sr25519 key instead of the babe'sAuthorityIdnewtype.GenesisStorageBuilder::build_storage()tobuild(inline with typical name used by builder pattern)
