test: enable namedChunks in cli-hello-world-lazy integration test (angular#41636)

This ensure that the name of the lazy chunk remains the same during updates. When not using `namedChunks` the id of the bundle is set to "deterministic", which means that the bundle name changes whenever the bundle is updated.
