Fix recording of federation stream token (#7564)
A couple of changes of significance:

 * remove the `_last_ack < federation_position` condition, so that
   updates will still be correctly processed after restart

 * Correctly wire up send_federation_ack to the right class.

+        This test checks that the federation sender is correctly sending back
+        FEDERATION_ACK messages. The test works by spinning up a federation_sender
+        worker server, and then fishing out its ReplicationCommandHandler. We wire
+        the RCH up to a mock connection (so that we can observe the command being sent)
+        and then poke in an RDATA row.
+
+        XXX: it might be nice to do this by pretending to be a synapse master worker
+        (or a redis server), and having the worker connect to us via a mocked-up TCP
+        transport, rather than assuming that the implementation has a
+        ReplicationCommandHandler.
