cmd-w doesn't close windows on mac after packaging app

[ghost]

• Electron version: 1.0.1
• Operating system: OS X 10.11.2

After using electron-packager@7.0.1 cmd-w doesn't close windows on mac, you have to click the red circle to close the window. However, it works when you execute the app with electron .

The Cmd-W only works when you have application menu in your app. When you run your app via the default app, a default application menu will be assigned, but it be gone after you packaged your app.
