[DeSoDog]

• add encryptedMessagingKeyRandomness, derivedPublicKeyBase58Check and ownerPublicKeyBase58Check to identity params
• set encryptedMessagingKeyRandomness on user after generating default key
• handle errors from identity if a derived (aka metamask) user is trying to encrypt/decrypt without encryptedMessagingKeyRandomess
  • sweet alert to tell user we need them to open identity to generate default key, take response from messaging group and update user in local storage, try encrypting/decrypting again if success and proceed with execution
• update types
