Fixed telling Ignition on Ghost start to inherit from a native error message

no issue

- this is a fix when starting Ghost and it cannot start because of a native error
- it could happen that a third library returns a native error, which will then be wrapped into an Ignition error
- we should tell Ignition to inherit from the error message, otherwise the error message is for example
  not directly visible in the CLI
