'Disable JS Checks for This File' Quick Fix Inserts Extra NewLine

[mjbvz]

From: microsoft/vscode#25405

TypeScript Version: 2.3.1-insider0425

Code

// @ts-check
const e = new Error();
e.x = 3;

1. on e.x select the Disable checks in this file quick fix

Expected behavior:
Code becomes:

// @ts-nocheck
const e = new Error();
e.x = 3;

Actual behavior:
An extra new line is added:

// @ts-nocheck
const e = new Error();
e.x = 3;

It seems an extra \n is returned in the quick fix insert text
