When a pull request is updated, the PR updater assumes that it can re-use the commit message from an old pull request commit. If the appropriate commit has been lost, however, we've seen strange behavior wherein the message from an unrelated commit is used instead.
In this scenario (i.e., when the old commit is missing), ideally Dependabot should regenerate the commit message. Unfortunately we currently don't have the metadata necessary to do so at the point where the updater is invoked in our internal service. As an interim solution, this change uses the PR title as a fallback commit message to prevent the confusing behavior described above.
