Improve logging around circuit errors

I was trying to diagnose this error from #1280 (comment 2998936)

2000-01-01T04:25:23Z  WARN tor_hsservice::helpers: Problem while accepting rendezvous request: error: Could not connect rendezvous circuit.: Could not establish circuit to rendezvous point: Tried to Establish a circuit to a rendezvous point 2 times, but all attempts failed
Attempt 1: Problem building a circuit, while extending to chosen HS hop: Circuit closed
Attempt 2: Problem building a circuit, while extending to chosen HS hop: Circuit closed

but it doesn't say which circuit failed (so I can't find the corresponding tor_proto::circuit::reactor logs)
