snapshot: make sure we'll never refine delta base from a reused source
The point of reusing delta from the source is to avoid doing computation when
applying a bundle. Refining such delta would go against that spirit.
We do not have refining logic in place yet. This code needed to be moved out
of the way before we could start adding such logic.
