Upgrade import to RN0.25+

[farwayer]

Starting in RN 25 React Native import wil change:

Requiring React API from react-native will be deprecated:
https://github.com/facebook/react-native/releases/tag/v0.25.1

Instead of:

import React, { Component, View } from 'react-native'; 

you should now:

import React, { Component } from 'react';
import { View } from 'react-native';

You can also try this codemod built by the community to automatically rewrite all the imports.
