tls: renegotiate should take care of its own state

In the initial version of this test there were two zero-length writes to force tls state to cycle. The second is not necessary, at least not now, but the first was. The renegotiate() API should ensure that packet exchange takes place, not its users, so move the zero-length write into tls.
