Update paths not triggered on rename if you have never opened a js/ts file

[mjbvz]

Steps to Reproduce:

1. Create an empty workspace with two ts files in it:

a.ts:

export const a = 1;

b.ts:

import { a } from './a';
console.log(a);

2. Close all files and restart vscode.
3. Without opening any ts file, use the explorer to rename a.ts to x.ts
