Returns a Props(TestKitBase, Boolean) object that can be used to create an EchoActor. The EchoActor echoes whatever is sent to it, to the TestKit's TestActor. By default it also echoes back to the sender, unless the sender is the TestActor (in this case the TestActor will only receive one message) or unless echoBackToSenderAsWell has been set to false.

	TestKitBase testkit,
	bool echoBackToSenderAsWell = true
