Title: An authentication failure from an API key should exit 1.

```bash
~/Development❯ HEROKU_API_KEY=xx heroku run rails console --app test-app
Running `rails console` attached to terminal... Authentication failure
```

The follow command should exit with a status of 1 because an authentication failure occurred that it could not recover from.
