Fixes https://xenitsupport.jira.com/browse/ALFREDAPI-541

• Is CHANGELOG.md extended?
• Does this PR avoid breaking the API?
  Breaking changes include adding, changing or removing endpoints and/or JSON objects used in requests and responses.
• Does the PR comply to REST HTTP result codes policy outlined in the user guide?
• Is error handling done through a method annotated with @ExceptionHandler in the webscript classes?
• Does the PR follow our coding styleguide and other active procedures?
• Is usage of this. prefix avoided?

See README.md for full explanation.

Everything looks good,
However when I try to render the file locally I get some API errors,
docker run -p 8888:8080 swaggerapi/swagger-editor

Not sure if this is due to the pretty-print or if this was always the case?
Looking into it still
