0.1.0 is specified if sinceTag is not specified

Describe the bug

In my workflow, I doesn't specify sinceTag， however, it fails with error:

/usr/local/bundle/gems/github_changelog_generator-1.15.0/lib/github_changelog_generator/generator/generator_tags.rb:138:in `filter_since_tag': Error: can't find tag 0.1.0, specified with --since-tag option. (GitHubChangelogGenerator::ChangelogGeneratorError)

My project has no tag named 0.1.0, so it should fail. However, since I don't specify any value for sinceTag, why action-github-changelog-generator pass 0.1.0 to --since-tag?

Any workaround to avoid this error?

For more infomation, please have a look at https://github.com/zillionare/ppw_0419_01/runs/2382578601?check_suite_focus=true

by the way, thanks for provide this great github action (it saved me since I have no need to learn ruby).
