If createNewCommitForAllInTarget = true is configured a commit might
identify more than one change. When trying to close changes on push
in ReceiveCommits this is not taken under consideration, instead it
tries to close the change of the first patch set that matches the
revision.
This could result in not closing changes even though patch sets
of the changes have been pushed into target.
