Previously, the case where SCMTool.get_commit_history returned None
was not graciously handled in rbt post leading to an exception. We now
explicitly handle this case and report this to the user.

Additionally, we now explicitly handle the case of a commit containing
an empty diff (e.g., if the commit was created with
git commit --allow-empty), which will not pass validation with Review
Board (as it doesn't allow empty diff uploads).
