title: TeamCity does not see changes in Git branch
body: <p>I have two git branches set up, dev and test.  The dev branch is frequently committed to, then periodically merged into test.  I have a teamcity project set up with the VCS root pointed to dev as the default branch, and test included in the branch specification of the VCS root (<code>+:refs/heads/test</code>).  Teamcity picks up changes to the dev branch just fine, but when merging to test, it doesn't detect when the merge is committed and sync'ed.  How can I get TeamCity to recognize the push to test and deploy appropriately?</p>
