873beca6d [tests] Rename NodeConn and NodeConnCB (John Newbery)
Pull request description:
Final step in #11518
NodeConn -> P2PConnection
NodeConnCB -> P2PInterface
This is basically just a rename. Should be an easy review.

"""Test message sending before handshake completion.

A node should never send anything other than VERSION/VERACK/REJECT until it's

received a VERACK.
|
|
|
|
This test connects to a node and sends it a few messages, trying to intice it

into sending us something it shouldn't.
