[JENKINS-14778] Polling doesn't see changes when watching two branches and merging into one of them

We have a two branches: feature and integration.

Jenkins was setup to poll the feature branch and merge it into integration before the build.

Everything worked fine.

But since occasionally we had to do explicit changes to integration, we added the integration branch to the branches to poll. From that point on jenkins didn't see any changes at all. It allways claimed there were no changes although there where new commits in both branches.

We set it back to poll only the feature branch and it works again.
