Subject: ListView doesn't show new 1st item currentItem is removed.

If the new 1st item becomes the currentItem after removal
it was positioned incorrectly because the currentItem is positioned
based on visibleIndex, which was updated after the currentItem
was updated.  Move visibleIndex update before currentItem update.
