test(heureka): fix ErrorBoundary className test assertion

hodanoori · hodanoori · commit a534acfeadc7 · 2026-03-13T16:15:08.000+01:00
Replace nodeName check with querySelector("div[class]") — the Component
renders a plain &lt;div&gt; so container.firstChild is always a DIV regardless
of the wrapper, making the previous assertion always fail.
