EmptyBodyDeserializer does not handle error responses

[pkoenig10]

What happened?

A void endpoint that returned an error did not result in an exception. The EmptyBodyDeserializer does not decode errors:

dialogue/dialogue-serde/src/main/java/com/palantir/conjure/java/dialogue/serde/ConjureBodySerDe.java

Lines 280 to 284 in bb92eac

	public Void deserialize(Response response) {
	// We should not fail if a server that previously returned nothing starts returning a response
	response.close();
	return null;
	}
