The sprint_29 branch is actually on 2aa5fa15c43e3299054d3fc65d279548efa75270 (other branches are unchanged)

Steps to reproduce:

1. Create a pipeline job
2. SCM with Git, target branch */sprint_${SPRINT_NUM} and SPRINT_NUM is set as global variable. Uncheck lightweight checkout.
3. The Jenkinsfile has a shared library imported, it also has PollSCM("* * * * *") in the triggers section
4. Trigger the pipeline once to apply the config in Jenkins
5. Polling log will find no change if you pushed something on sprint_29 on the branch. (no need to commit anything on the shared library)
