release v0.22.0

• fix redirect flow
  • redirect flow depends on initializing the auth0 lock with a state param:
    Auth0.getAuth0LockInstance().show({ auth: { params: { state: auth0NonceState } } });
  • the bug was that show() was being called without being passed auth param
    Auth0.getAuth0LockInstance().show()
