[PATCH wayland 4/5] client-test: test posting no-mem error on client destruction

[Marek Chalupa]

while client is being destroyed, it destroys all its resources.
Destroy handlers are called for the resources and if some
destroy handler post no memory error, we get crash, because
the display resource is NULL (it is destroyed as a first resource)
