Ephemeral server endpoint logs incorrect listening address

[exarkun]

On running:

twistd web --listen onion:12345

The following is eventually logged:

2018-07-16T12:57:10-0400 [TorControlProtocol,client] Started hidden service port 12345
2018-07-16T12:57:10-0400 [TorControlProtocol,client]   listening on <REDACTED>.onion.onion

Note the .onion.onion suffix (which should instead be .onion - just once)

Hmm, what version was this with? 18.0.2 and higher have mostly-new onion code, I see the following when running twistd:

Ugh. Sorry. Somehow I ended up with a very old version. With 18.0.2 I see the same correct behavior as you.
