ZauberNerd 31a0b8788f Add jest mock for 'PushNotificationManager' ...

Summary:
`PushNotificationIOS` is a library that makes use of the
`PushNotificationManager` native module.
This commit adds a jest mock for its native module so that code that
uses `PushNotificationIOS` can be tested using jest.

In order to enable behaviour in unit tests it is possible to replace or
overwrite the mock implementation, see the [jest guide on
mocks](https://facebook.github.io/jest/docs/mock-functions.html).
By doing something similar to:
```javascript
import { NativeModules } from 'react-native';
const { PushNotificationManager } = NativeModules;
// mock 'checkPermissions' to return a different value than the default:
PushNotificationManager.checkPermissions.mockImplementationOnce((callback) => {
    // execute callback in next tick to enable async behaviour
    process.nextTick(() => callback({
        alert: false,
        badge: false,
        sound: false
    }));
});
// execute unit tests for code that makes use of 'PushNotificationIOS'
```
