"Move to new file" does not copy namespace imports

Code

// ./src/foo.ts
export const whatever = 1;

// ./src/index.ts
import * as foo from './foo';

const bar = foo.whatever;

export default bar;

Expected behavior:
When copying the line const bar and actioning the "Move to new file" command, the new file contents should be:

import * as foo from './foo';
export const bar = foo.whatever;

Actual behavior:
The new file contents are:

export const bar = foo.whatever;

The foo namespace import is missing, which creates errors:

I encountered this today and got 99% of the way through writing a bug report before I found the duplicate 😢. This still happens in typescript@3.9.0-dev.20200309

I'll say "TS2686" now to add that search term, as it's a common error to get on the destination side if the missing import is something like import * as ReactDOM from "react-dom".

This was fixed by #38377; #35591 was a dupe of this issue.
