update-react-imports adds extra import * from React

When an import is defined as

```
import React, { useState } from 'react'
```
(usually due to automatically added imports)

The update-react-imports codemod transforms it to 
```
import { useState } from 'react';
import * as React from 'react';
```

Instead of just
```
import { useState } from 'react';
```
