Fix pull request update showing too many commits with multiple branches (#22856)
When the base repository contains multiple branches with the same commits as the base branch, pull requests can show a long list of commits already in the base branch as having been added. What this is supposed to do is exclude commits already in the base branch. But the mechansim to do so assumed a commit only exists in a single branch. Now use `git rev-list A B --not branchName` instead of filtering commits afterwards. The logic to detect if there was a force push also was wrong for multiple branches. If the old commit existed in any branch in the base repository it would assume there was no force push. Instead check if the old commit is an ancestor of the new commit.
