Create ref for new patch set on direct push (second try)

If a change is in review and a new commit that has the Change-Id of
this change in its commit message is pushed directly, then a new patch
set for this commit is created and the change gets automatically
closed. The problem is that no change ref for this new patch set is
created and as result the change ref that is shown for the new patch
set in the WebUI and which is contained in the patchset-created event
is invalid.
