Typescript emit issue

Tested on versions

• 2.7.2
• 2.8.1
• next

Repro

• install deps (npm install)
• run test (npm test)
• take a look at ./dist/b.js

Description

Given a.js and b.js as follows:

// a.js
const Obj = {};
export default Obj;

// b.js
import Obj from './a';

Obj.fn = function() {};

The following emit is produced for b.js -- missing the import of Obj and resulting in a runtime error:

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
Obj.fn = function () { };
//# sourceMappingURL=b.js.map
