Ilya Sinitsyn 85b37bea49 Fix GetBestSize() for hidden controls in wxGTK
gtk_widget_get_preferred_size() return zero size if the GTK widget is
hidden, so show it temporarily in order to find its real preferred size.

Add a unit test checking that the best size of a hidden wxChoice is now
determined correctly.
