surf: fix directory construction

If a git Tree is a subtree then it no longer contains the path
information while traversing it. The traversal will only carry the
path with it if it does not skip directories, which in the case of
`entries`, it does.

To remedy this, the `path` method is used to pass the information to
`from_entry` instead.
