CreateBranch: Allow revision in input to be empty

If a revision in the input is not specified we default to the HEAD
revision, but when the revision in the input was empty we failed with
400 Bad Request. Be more tolerant and consistent and default to the HEAD
revision too if the specified revision is empty.
