snapshot: refine candidate snapshot base upward
Once we found a suitable snapshot base it is useful to check if it has a
"children" snapshot that would provide a better diff. This is useful when base
not directly related to stored revision are picked. In those case, we "jumped"
to this new chain at an arbitrary point, checking if a higher point is more
appropriate will help to provide better results and increase snapshot reuse.
