Error when deploying to an Exoframe instance with docker network name other than exoframe

When I try to deploy to an Exoframe instance that uses "traefik" as docker network instead of "exoframe" I get TypeError: Cannot read property 'Aliases' of undefined.

I think the issue is on line 7 and 8 in [formatServices.js](https://github.com/exoframejs/exoframe/blob/master/src/util/formatServices.js).
