Leave exposition to invalidate() in QWasmWindow::raise&lower 

The window may be in a temporary state where the window()->handle() is
not yet set up. This makes an expose event with isExposed == false being
issued, which makes the window not refresh, especially when a async expose
request follows shortly after.
invalidate() handles this case itself as it issues a request to the
compositor which exposes the window at the right moment.
