bundle: when forcing acceptance of incoming delta also accept snapshot

Snapshot where never considered reusable and the unbundling side always tried
to find a delta from them. In the `forced` mode this is counter-productive
because it will either connect two delta-tree that should not be connected or
it will spend potentially a lot of time because creating a full snapshot
anyway.

So in this mode, we accept the full snapshot as is.

This changeset is benchmarked with its children so please do not split them
apart when landing.
