It is wise to run `flow` but it will not check much since those types are not used anywhere yet. Better way to test this differential is to log to console outputs of
`CryptoModule::generateNewPrekey` and `CryptoModule::getOneTimeKeys()` and ensure those outputs match presented types. Note that type for prekey is somewhat different. It was changed to make sure that
there is only one id <-> key pair inside `curve25519`.
