Only use IntentAndroid on android

Summary:
For other platforms such as React VR it doesn't make sense to use `IntentAndroid` native module and it should use `LinkingManager` instead.

The code used to be:

```
const LinkingManager =
  Platform.OS === 'android'
    ? NativeModules.IntentAndroid
    : NativeModules.LinkingManager;
```

This diff changes the behaviour back to what it used to be.
