test/stages: export tree and compare that

Browse source 
Instead of checkpointing the tree and then accessing the generated
tree inside the store via the `map_object` function we not just
export the tree and use that. This better hides the internals of
the store and also allows us to activate on-demand building that
does not rely on checkpoints being implicitly built like exports.
