Fix CheckedTextViewTest#testChecked

The test calls ListView#setItemChecked. setItemChecked updates the
ListView's map of checked widgets properly and then asks for a
relayout. The ListView seems to only update the children that are
visible, because fixing the layout causes the views themselves to become
checked properly.
