chore(ssh): drop the temporary reconnect-replay diagnostic

Served its purpose: it is what turned 'the panes look blank' into
replay=false, replayLen=0 on every pane, and then into replay=true with real
byte counts once the relay fix landed. The permanent log line keeps the boolean,
which is the part worth having.
