Fix flaky test in CreateMergePatchSet

Browse Source 
ChangeIT#createMergePatchSet was flaky. For some reason, even though the patchset
was created, after the second creation (e.g previously line 3245) one of the
followings happened around 50% of the times:

1. changeInfo.revisions contained 3 revisions, instead of 2.
2. changeInfo.currentRevision was null.

Another finding was that when I removed the flag CURRENT_COMMIT, none of those bugs
occurred.

One theory is that something is really wrong with creating a merge patchset with
the same parent: The change in "dev" is both a parent and a grandparent of the
change in line 3245. This should be investigated further, but this change only
fixes the flaky test.
