fix(tvix/glue/tvix_store_io): remove early return r/7998

Doing the fetch comes up with the root node, but we still need to
descend from there to the desired subpath.

Move things around to ensure the fetch case also only sets root_node.

This logic should probably be moved into smaller, easier to consume
functions.
