[JENKINS-30350] Jobs get triggered twice from polling git scm

We are seeing a weird problem occasionally on our jenkins setup ver 1.627

git client 1.19

git plugin 2.4 on ubuntu machine.

I have a job configured to poll scm every 5 minutes

sometimes, when there is a change the job gets triggered twice

once with the relevant changes and the second time says "no changes"
