tst_qquicktableview: fix warning about missing JS function

Change 35fdf3a7b7 added a binding to a function in one of
the QML files used for testing (plaintableview.qml). The
problem is that this file is also used from other places
where we wrap a QSharedPointer that points to the model
inside a QVariant. And when assigning that variant to
a TableView, the QML binding will see the QSharedPointer, and
not the model it points to. And hence complain that the
model doesn't have the API that is exported from the
model.

The easy fix is to just create a new QML file for the
new test added, that has the binding, but assigns
a QVariant that wraps the model directly without
usign a QSharedPointer.
