title: WL.Client.Logout() when app is shutdown
body: <p>I'm having a problem with <code>wl.client.connect()</code> and <code>wl.client.logout()</code>.</p>
  
  <p>If a user logs in successfully, a token and roles are remembered among other things. We save these vars while in our challenge handler functions of the <code>wl.client.connect()</code> auth.</p>
  
  <p>But if they login, then shut down the app, opening the app again and trying to log in, I get a <code>wl.client.connect()</code> onSuccess, but since it has not gone through the challenge handlers, I don't get any tokens and roles that I need to save.</p>
  
  <p>Do I need to, or is it possible, to run <code>wl.client.logout()</code> when they kill the app?</p>
