Detailed Description of the Pull Request / Additional comments

Commit bc69d1a99a adds code that closes
the window when the last tab is being closed, but code that should only
be executed when closing one of multiple open tabs continues to be
executed. This leads to App::_RemoveTabViewItem trying to call
TabView::SelectedIndex(1) when there is only 1 tab remaining in the
TabView, resulting in an argument exception.
