This fixes #5555
When there's a finalized check point, a node enters in a migration phase to delete states that's not on the archival point. In previous iteration, a node will regenerate the state if the state does not exist on the migration point but that quickly becomes too buggy as the underlying block may not exist as well.
This PR went with the simpler approach to only preserve the state that is on the archival point.
