Jerry Zhang 51276c1832 patch-id: use stable patch-id for rebases
Git doesn't persist patch-ids during the rebase process, so there is
no need to specifically invoke the unstable variant. Use the stable
logic for all internal patch-id calculations to minimize the number of
code paths and improve test coverage.
