   8 * be signed in using a different account than their chrome profile.  When these
   9 * users upgrade to the v2 app, their host list will be empty and it is not
  10 * obvious why.  remoting.AppsV2Migration shows a migration tip to the user to
  11 * sign in to their previous accounts if necessary.
