John Newbery dad596fc37 [tests] Make NodeConnCB a subclass of NodeConn
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.

NodeConn can now be swapped out for any other implementation
of a low-level connection without changing client code.
