title: Google Smart Lock dialog for saving credentials does not appear when testing
body: <p>I am trying to save a user's facebook credentials to Google Smart Lock, but I am having difficulty testing. I was able to display the prompt to save once, but after I went into my saved passwords (passwords.google.com) and deleted the saved credentials, the prompt is not appearing anymore!</p>
  
  <p>I went into google settings and made sure to delete the app from the "never save" section, but it is still not appearing. When I call Auth.CredentialsApi.save(), it is returning with a resolution of "null" and message "The current app is blacklisted"</p>
