test: fix render.refresh tests to use .node() for updateNode calls

The updateNode function expects raw DOM elements, not D3 selections.
Updated test expectations to call .node() on selections before passing
to updateNode mock.

Also added url option to JSDOM constructor to enable localStorage
support, which is required by d3-zoom.
