sshpeer: reflect actual command activity one handshake

The output from devel-peer-request is expected to give data about request and
roundtrip done to the server. Changeset a9cffd14aa04 changed some of that by
grouping hello and between commands call. However, the old sequence of command
was "emulated" in sshpeer.

Update the sshpeer to reflect this grouping of commands and update the tests
that use it.
