/query set the status bar to [connected] whatever the connection
state. Before /connect, it made the status bar say [connected] while
the client had no session.
/query now reads the connection state with the nick, as /window does,
and shows [connected] only while the client is connected,
[disconnected] otherwise. TestQueryConnectionState types /query bob,
connected and not, and checks the status bar. It names the two status
texts as constants, because the linter asks for one once a third copy
appears.
