Fix textShadowOffset error without width or height

Summary:
textShadowOffset design is `ReactPropTypes.shape({width: ReactPropTypes.number, height: ReactPropTypes.number})`, so either width or height is optional.
Unfortunately, in Android implementation, it is my bad not handling optional case and lead to an exception.
Thanks kohver for reporting [this issue](https://github.com/facebook/react-native/pull/4975#issuecomment-213006641)

**Test plan (required)**

*Before this fix*
1. Modify TextExample.android.js to `<Text style={{fontSize: 20, textShadowOffset: {height: 10}, textShadowRadius: 1, textShadowColor: '#00cccc'}}>` which really raise a redbox.

*After this fix*
1. Test original TextExample.android.js textShadowOffset works well.
2. Modify TextExample.android.js to `<Text style={{fontSize: 20, textShadowOffset: {height: 10}, textShadowRadius: 1, textShadowColor: '#00cccc'}}>` which works well without redbox.
