title: Smoosh iOS SDK startConversation doesn't create user?
body: <p>I have Smooch working with Meya, embedded within my iOS app. When I <em>send</em> a message, the user Smooch/Meya user is created as expected. However, when the user does not send a message, and my app only calls startConversation, no user is created.</p>
  
  <p>I've tried it with both calling the login method and not calling the login method.</p>
  
  <p>Here is what I'm doing now:</p>
  
  <pre><code>Smooch.initWith(settings) { (error: Error?, _: [AnyHashable: Any]?) in
    if error == nil {
      Smooch.login("\(id)", jwt: jwt) { (error: Error?, _: [AnyHashable: Any]?) in
        if error == nil {
          print("login complete")
          Smooch.startConversation { (error: Error?, _: [AnyHashable: Any]?) in
            if error == nil {
              print("started conversation")
            }
          }
      } else {
        print("error logging in")
        print(error)
      }
    }
  }
  </code></pre>
  
  <p>And this results in the following log:</p>
  
  <pre><code>login complete
  started conversation
  </code></pre>
  
  <p>I have done a request to the get appusers endpoint and I see that <code>"conversationStarted":true</code>, however, no user has been created in Meya.ai.</p>
