Error after deploying

[pietroalbini]

When trying to deploy a version, after the build finished the bot posted this error:

There was an error when running deploy_app: CommandError("error decoding response body: invalid type: string "scheduler:standard", expected i64 at line 1 column 41")

Just tested this out using staging - I believe the build and deploy are happening fine, but the bot is choking on the response from the Heroku API. Looking into this further.

Fixed in #47
