False bailout with deep require

[doochik]

// root.js
const { foo } = require('./bundle.js');

// bundle.js
module.exports = {
  foo: require('./foo.js'),
  bar: require('./bar.js'),
}

In this case bar is not exported, but required and minifier can't eliminate this code.

Compiled code looks like this

/***/ (function(module, exports, __webpack_require__) {

module.exports = {
    "bar": ((__webpack_require__(4)),null),
    foo: __webpack_require__(5)
};

/***/ }),
