QToolTip: don’t close again on Close event 

Prevent recursion: hideTipImmediately() calls QWidget::close(),
which will soon start calling QWindow::close(), which
will send another close event.

Fix this by calling hideTipImmediately() only for Close
events not targeted for the tip label.

Task-number: QTBUG-46701
