wayland: sync() when destroy()

Before pushing a the new frame, the render() method calls sync() to flush the
pending frames. Nonetheless, the last pushed frame never gets rendered, leading
to a memory leak too.

This patch calls sync() in the destroy() to flush the pending frames before
destroying the window.

Also a is_cancelled flag is added. This flag tells to not flush the event
queue again since the method failed previously or were cancelled by the user.
