Throw error for empty CHANGELOG data

What problem do you want to solve?

If the configuration identifies that release notes should be pulled from the CHANGELOG, errors are thrown if the CHANGELOG file cannot be found or the release data cannot be found in the CHANGELOG. But, if the release notes are found, but are empty, there is no error, but this is usually an error in the CHANGELOG itself.

What is the proposed solution?

Update app to generate error and fail if CHANGELOG release notes are empty.
