▶ ./changelogger release v0.8.2
No Changes -> No Changelog for v0.8.2 created

In both cases, no real Changelogs were present. The difference is:

• v0.8.1 had empty changelog files
• v0.8.2 had no log files at all

Expected behavior

If no real logs exists, no changelog release is created and Changelog.md will not be changed.
