Add a test for ::row-changed vs node refs

Browse Source 
Test that filter models propagate ::row-changed if there is
an external reference on the node, and not otherwise. This
is showing up in buggy icon view behaviour, where the icon
view is not redrawing if the content changes in a model that
is below a filter model.
