Import React in a allowSyntheticDefaultImports: false friendly way.

Otherwise you'll see the following error:

```
node_modules/react-redux/es/components/Context.d.ts:1:8 - error TS1259: Module '"./node_modules/@types/react/index"' can only be default-imported using the 'allowSyntheticDefaultImports' flag

1 import React from 'react';
         ~~~~~

  node_modules/@types/react/index.d.ts:55:1
    55 export = React;
       ~~~~~~~~~~~~~~~
    This module is declared with using 'export =', and can only be used with a default import when using the 'allowSyntheticDefaultImports' flag.
```
