checkLoginAfterRefresh should check for isMobile

[ieow]

  checkLoginAfterRefresh = (response) => {
    if (response.status === 'connected') {
      this.checkLoginState(response);
    } else {
      window.FB.login(loginResponse => this.checkLoginState(loginResponse), true);
    }
  };

if response.status is not connected, it is trying to call FB.login without checking for mobile. (isMobile) This is causing unexpected popup on mobile
