Move to new file refactoring does not observe quoteStyle preference

Code

1. In VS Code, configure "typescript.preferences.quoteStyle": "single"

2. For a ts file:

class Foo { }

console.log(new Foo())

1. Run move to new file on Foo

Expected behavior:
Created import uses single quotes:

import { Foo } from './Foo';

console.log(new Foo())

Actual behavior:
Added import uses double quotes:

import { Foo } from "./Foo";

console.log(new Foo())

I confirmed that we do configure the quoteStyle before requesting the refactorings
