fix(read-tree): Don't import default.nix sibling expression

Browse source 
If a folder contains a `default.nix`, Nix expressions contained in
adjacent files should not be imported (they might be things like a
`shell.nix` or a `deps.nix` which do not evaluate to derivations).

The tree traversal still continues for all children folders of a
folder with a `default.nix`.
