Squirrel shortcut target is not correct, app launches after install but shortcut does nothing.

Node v8.9.4
electron-forge app with default settings no asar
Windows squirrel installer. May be related to #788

Issue is that when I build executable and run it, the app installs correctly and starts on first instance. When I close the app and start it again, it doesn't work, app does not get launched.

I believe that I am handling squirrel and app.quit() events correctly:

`
if (require('electron-squirrel-startup')) app.quit()
`
and
```

var cleanUp = function(event) {
if (appWindow) appWindow.close()
// app.quit()
}

app.on('before-quit', cleanUp)
```

The application works as expected in dev mode and also when running the packaged exe directly (before it's packed into the squirrel installer).
The problem is only apparent when running the squirrel installed application.

After doing some more research, I found that the issue is that the created shortcut points to an executable that is not inside a version folder. It's the same problem described in this issue.
electron/windows-installer#169
I'm still looking into exactly what configuration options needs to be adjusted, as I'm just using electron-forge defaults.
