title: missing Change-Id in commit message footer during push to gerrit
body: <p>Here is my configuration;</p>
  
  <p>on the server:</p>
  
  <p>os: Red Hat Enterprise Linux Server release 6.7 (Santiago)</p>
  
  <p>git 2.7.1 </p>
  
  <p>gerrit 2.12.2 </p>
  
  <p>on the client:</p>
  
  <p>Rational Application Developer v9.0 </p>
  
  <p>Egit v4.2 </p>
  
  <p>Mylin Reviews Connector: Gerrit v2.9 </p>
  
  <p>When I try to push a change to gerrit ("Push upstream") , it fails with the missing change id error message.</p>
  
  <p>I did some googling, and installed the commit-msg hook in the .git/hooks directory of the local repo.</p>
  
  <p>The change id is there in the commit message, but there is a bunch of comments added by the (mylin client I guess) after that.</p>
  
  <p>Please advise. Thanks in advance.</p>
