Major DERP: Appp was binding on 127.0.0.1

Heroku didn't seem to work and the web process ended up being sigkiled
by heroku

    Stopping process with SIGKILL
    exited with status 137

Generating some:

    at=error code=H10 desc="App crashed" method=GET path="/"
    host=na-city-suggestions.herokuapp.com
    request_id=606161f9-3241-4d34-ba45-b6f58da84ba6 fwd="184.162.253.172"
    dyno= connect= service= status=503 bytes=

But it was because app never binded on 0.0.0.0:$PORT
