Title: Do not send "addr" twice to clients sending "verack"

In order to handle peers that omit the "verack" message
#complete_handshake is called both on "version" and "verack" messages.

Until now this method triggered an "addr" command to the peer
unconditionally, though, so proper clients received the message twice.
