fix: typo, more visibility for fatal errors, no endless failure loop

- Fixed error message when no decent SECRET_KEY is supplied.
- The messages of a fatal errors are surrounded by newlines for better
  visibility.
- The supervisord in the Docker image will fail if the uwsgi can not
  start the application and will not stay in a never ending loop of
  errors.
