[JENKINS-60159] Multibranch pipeline - existing branch seen as first time build

Sometimes when building an existing multi-branch pipeline, the build is incorrectly regarded as first-time. The console log shows "First time build. Skipping changelog." ,and the build-overview says "no changes", both incorrectly.

 

This results in confusion whether commits/merges have been done correctly as they are not visible.
