This was just a mistake, fixed.

 public:
-    StubChromeClientForSPv2(WebLayerTreeViewImplForTesting::LayerListPolicy layerListPolicy)
-        : m_layerTreeView(layerListPolicy)
+    StubChromeClientForSPv2() : m_layerTreeView()
     {
         m_layerTreeView.setRootLayer(*m_paintArtifactCompositor.getWebLayer());
     }
