Gdk-Win32: Correct handling of transient state changes 
gdk_win32_window_set_transient_for() behaves incorrectly when
called in sequence with the same arguments. This fix ensures it
always operates correctly.
In some cases this function gets called multiple times with the
same arguments, e.g. when tooltips are shown.

See issue #1214
