Gerrit does not create depency for patch

1. Select a patch from Gerrit.
   Let's call this patch A.
2. Reset your local branch to A's parent, listed on it's Gerrit page.
3. Cherry-pick patch A to your local branch.
4. Create a new commit on top of patch A.
   Let's call this patch B.
5. Push your local branch to Gerrit, using the same branch like patch A.
   Patch B will appear in Gerrit but it will not show the depedency to A.
   This is the output of git:

   C:\Users\rob\Git\creator>git push origin master:refs/for/master

    ! [remote rejected] master -> refs/for/master (no changes made)
   error: failed to push some refs to 'ssh://codereview.qt-project.org/qt-creator/qt-creator'
   

Instead, the dependency to A should be shown even if no changes were made to A.
