Problem: The commit id is not added to RPMs changelog when using release tag

[mamedin]

When using release tag instead of branch name to build packages the RPM changelog is missing the AM and SS commit id.

For instance:

https://jenkins-ci.archivematica.org/job/am-packbuild/job/rpm-jenkinsci/398/
https://jenkins-ci.archivematica.org/job/am-packbuild/job/rpm-jenkinsci/399/
