I just installed Gerrit and I wanted to do a push to it, but I'm getting an error regarding `Change-Id`, but it appears to be in the commit it's complaining about.

```
$ git push gerrit HEAD:refs/publish/my-branch

! [remote rejected] HEAD -> refs/publish/my-branch (missing Change-Id in commit message footer)
error: failed to push some refs to 'ssh://user@ci:29418/Project'

```

I assume that this is because of previous commits that are without `Change-Id` because they were made prior to having the hook. How can I update all previous commits to add the `Change-Id`?
