Empty state is wrong when comparing merge request versions

### Steps to reproduce - push an empty commit to a merge request or squash existing commits - click `Compare with previous version` on discussion tab ### Example Project https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28216/diffs?diff_id=41550743&start_sha=b532c55778e4d42654431bbc4dc8dbda134b26c2 ### What is the current *bug* behavior? The top of the changes tab mentions `Changes between latest version and version ...` but the empty state claims `No changes between ... and master` (which is wrong): ![wrong-empty-state](/uploads/d044401cee5f488b9ade67ce49373de1/wrong-empty-state.png) ### What is the expected *correct* behavior? Display `No changes between latest version and version ...` in the empty state.
