Windows: Fix bug where windows stopped painting after a restore.

Browse Source 
This is an improvement over 6800728d where we only fixed it if
the window was in "normal" state (Qt::WindowNoState) before
minimizing.

With this patch, if the window was previously maximized or
full-screen it will also get the expose events when being
restored.
