extensions: always include traceback when extension setup fails

I have spent a lot of time debugging extensions that failed to load
because we don't include a traceback and I didn't realize I could get
traceback for the extension failure with --traceback. Let's just turn
them on by default, since it should be rare that the user sees these
tracebacks anyway (and if they do, it's not so bad if the extra
traceback pushes them a little harder to report the problem).

Since we already had a test case with --traceback and one without, I
just removed the one with the flag.
