[JENKINS-56107] GIT_BRANCH sometimes is not populated

For some reason some builds (maven job) doesn't populate `${GIT_BRANCH}`

I haven't found any pattern to this - my only suspicion would be "build strategy" that sometimes selects non-master branch (solution to problem with simply building all branches from https://issues.jenkins-ci.org/browse/JENKINS-11337)
