Bug: expandAllTreeNodes works incorrectly when generateIdFromPath is disabled

[AndrewBoklashko]

Sandbox: https://codesandbox.io/s/reactdatagrid-expand-hierarchy-issue-toddm2?file=/src/App.js

Steps to reproduce the issue:

1. Open the sandbox link
2. Click 'Expand All' button

Expected result: all tree nodes are expanded Actual result: only level 1 nodes are expanded

Also it would be helpful to have typescript definitions for expandAllTreeNodes and collapseAllTreeNodes.
