WebHook posts wrong commits for rebase

Similar to how https://github.com/gitlabhq/gitlabhq/issues/8401 has an empty payload on the initial creation of a branch, a rebase causes too many commits to be emitted. The intervening commits are listed. Trying to figure out the set of reviewers that are involved with the branch is thus made impossible.
