window: Properly destroy tooltip windows when parent window is destroyed

If we destroy a window with an active tooltip, we leave the tooltip
hanging around.  Call tooltip destructor when destroying a window.
This fixes the stuck tooltip observed when unplugging a monitor with
an active tooltip on the panel.
