The fix in #16528 now correctly throws Uncaught TypeError: Cannot read properties of undefined (reading 'r') when disposing last instance from a mesh (https://playground.babylonjs.com/?snapshot=refs/pull/16528/merge#0E9WBX). This is identical to the thin instance case in forum (https://forum.babylonjs.com/t/removing-thin-instances-vs-gpupicker/57989).

The correct sequence is for the user to update the picking list after dispose/matrix buffer. While this repo isn't the primary culprit, its still annoying when the error crashes user app during dev. This PR adds a stricter check to the callback and performs some minor cleanup missed in the previous fix.
