Make bisect/basic.go test more concrete

- check out a non-main branch before we start
- add authors to expected commits so that we can see whether the commits show an
  asterisk
- explicitly check what the top line displays after bisecting has started

This shows that the detached head shows an asterisk, which we don't want. We'll
fix that in the next commit.
