title: react-native push-notification-ios geMessage and getAlert return undefined
body: <p>I am using react-native <code>0.62.2</code> and @react-native-community/push-notification-ios <code>1.4.0</code>. I recently upgraded from <code>0.61.5</code> and <code>1.0.3</code> respectively. Now, when I a user taps on a notification, the <code>getMessage</code> or the <code>getAlert</code> API returns undefined. The notification is displayed as expected on the phone. When I print the received notification, I see below:</p>
  <pre><code>{ _data: 
     { alarmId: '-MER20hCArS72IzmKDE1',
       uid: '-MBKyOBWjSzGtY-LPi4t'
     },
    _remoteNotificationCompleteCallbackCalled: false,
    _isRemote: undefined,
    _badgeCount: undefined,
    _sound: undefined,
    _alert: undefined,
    _title: undef2020-08-11 11:16:06.862887+0530 MyApp[1160:811760] SocketStream write error [0x280130fc0]: 1 32
  ined,
    _category: 'i_am_up',
    _fireDate: undefined
  }
  </code></pre>
  <p><code>_alert</code> appears to be undefined in the above data but the notification is displayed correctly with the right alert message. In fact, not just the alert but other fields such as <code>fireDate</code>, <code>sound</code> are also undefined. I am not sure what is causing the problem.</p>
  <p>Below is the call to schedule a notification</p>
  <pre><code>PushNotificationIOS.scheduleLocalNotification({
        fireDate: time,
        alertBody: alertBody,
        soundName: soundName,
        userInfo,
        category: category,
        repeatInterval: repeatInterval
  })
  </code></pre>
  <p>P.S. I have also opened a github issue for this problem at <a href="https://github.com/react-native-community/push-notification-ios/issues/169" rel="nofollow noreferrer">https://github.com/react-native-community/push-notification-ios/issues/169</a> which also contains steps to reproduce using the example project in the repository.</p>
