Kyle Corbitt 2d921eeb70 Resolve react flow definitions
Summary:Currently, we're not taking advantage of Flow's built-in type definitions for the React library in all cases because Flow's definition uses `declare module react` and this file uses `import('React')`, which Flow thinks is a different library. After this change, the following starts working which didn't before:

```js
import { Component } from 'react-native';

class MyText extends Component<void, {text: string}, void> {
  render() { return <Text>{this.props.text}</Text> }
}

// Correctly throws a Flow error for the missing "text" prop
const renderedText = <MyText />;
```
