The /app/server and /app/test should be outside the app folder

[Ouadie]

The app folder must contain only source code related to the app everything else should be put next to the app folder. Something like this:

-bin/
--server/
----server.js
----server-ssr.js
----webpack-dev-server.js (moved from root to /bin/server)
--start.js (old server.js)
--start-ssr.js (old server-ssr.js)
--start-webpack-server
