When `heroku ps` shows no processes, reset the scaling with `heroku ps:scale web=1`

I recently changed the name of the process that runs my hubot in an effort to keep it from timing out. What I didn't realize is that I had to change the scaling in order to make it work.

So, when heroku ps shows no processes and your app won't seem to show activity in heroku logs, then you might need to reset the scaling with heroku ps:scale web=1, changing web to whatever the name of the process is in your Procfile.
