Not possible to get version on detached HEAD (GitLab Runner)

[WebDucer]

Hello.

We use GitLab CI and GitVersion (within CAKE build). Most of the time it works great. Today we got the following error, that Gitversion can not determine the version.

As I can see, Gitversion has found the branch, that have the detached commit, but not use the information for getting the version.

We use version 3.6.5 of GitVersion at this time.
