Allow empty "unreleased" section

[datenreisender]

We always keep an unreleased section in our CHANGELOG.md, it is just empty for releases. With #43 this is now prevented. It would be nice, if an empty unreleased section is allowed and only if there is stuff in it, an error is shown.

I see! I think if the unreleased section is empty it makes sense to allow it.

I think all that would be needed is to modify the block linked to below to check if the unreleased section has a non-empty body property.

I will try to get this feature added soon, but in the meantime a PR is welcome 😄
