[Bug] `"search-node-modules.useLastFolder": true` is not working

[wenfangdu]

VSCode: 1.68.0
Search node_modules: 1.3.0

Enable search-node-modules.useLastFolder, open a file that has node_modules not in the root level, e.g.

- root
  - parent
    - node_modules
    - file

Use extension.search, and the extension throws "Search node_modules: No node_modules folder in this workspace.".
