Blank login page on first load

[haydenrou]

From the README:

On first load, the app displays a blank beige screen instead of the login screen. Temporary fix is to add console.log(process.env.FACEBOOK_APP_ID) right inside of the module.exports at the top of the frontend/config/environment.js file. You can then refresh the page (no need to kill Docker) and this should fix it. You can now remove the log.

The error displays in the console as follows, until you console.log per the above comment.

• Uncaught Error: Expected configuration value appId to be defined for provider named facebook-connect
