"import *" seems to be broken

input:

```jsx
import * as THREE from 'three'

export default function(name) {
return THREE[name]
}
```

output (compilation_level: SIMPLE_OPTIMIZATIONS):

```jsx
import * as THREE from 'three'
export default function (a) {
return THREE[a]
}
```

👍

input:

```jsx
import * as THREE from 'three'

export default function(name) {
const o = new THREE.Group()
return THREE[name] + o.id
}
````

output:

```jsx
import { Group } from 'three'
export default function (a) {
let b = new Group()
return THREE[a] + b.id
}
```

😕 it took away the `THREE` import for some reason, `return THREE[a]` is now invalid.
