We need to destroy the compositor after Xwayland terminated and after the internal Wayland connection is destroyed. This means when destroying the Workspace we may no longer destroy the Compositor at the same time. Also we need to ensure that other tear down functionality doesn't call into the no longer existing internal client connection. With this change kwin doesn't crash when exiting with Wayland and/or X11 windows still open.
