Issue:
Confusing warning message for parameters in FSHOnly mode
`parameters` is an IG-only property. When running in FSHOnly mode, a warning is issued when parameters is present. However, because other configuration values are added to the configuration's `parameters` array, a confusing error message can occur in the following situation:
- `config.yaml` does _not_ contain `parameters`
- `config.yaml` contains `copyrightyear` or `releaselabel`

The resulting warning message is: `The FSHOnly property is set to true, so no output specific to IG creation will be generated. The following properties are unused and only relevant for IG creation: parameters.`

Pull request description:
Fix FSHOnly warning bug
This fixes #553.

As the issue description notes, we were emitting a warning incorrectly when `releaseLabel` and/or `copyrightYear` were present in the config. Since these fields get includes into `parameters`, the warning would not `parameters`, but this is confusing, because the user is not necessarily aware that `releaseLabel` and `copyrightYear` go into `parameters`. This PR fixes that bug by changing the warning to directly use the fields in the yaml file.
