(PUP-11428) Remove useless test

The test passed an instance of `TestClient` which caused the daemon to call
`new` on the instance, and so the daemon appeared to "do nothing", when actually
it raised a `NoMethodError`, which was logged, but never printed. Instead pass
the `Puppet::Configurer` class.
