VirtualKeyboard on Wayland Compositor fails to send Enter key event to clients

VirtualKeyboard, when used as part of QtWayland Compositor, fails to send Enter key event to application.

The issue is in

QWaylandXkb::toKeysym

where it falls to the wrong code path because the QKeyEvent::text() for this key event is not empty. On the client side it is then received as QKeyEvent(key = 0. text = "\n") - the key code is lost.

Attached is a quick patch that fixes this issue.
