In d1bbbe45df8 (bisect--helper: reimplement `bisect_run` shell function
in C, 2021-09-13), we ported the `bisect run` subcommand to C, including
the part that prints out an error message when the implicit `git bisect
bad` or `git bisect good` failed.

However, the error message was supposed to print out whether the state
was "good" or "bad", but used a bogus (because non-populated) `args`
variable for it. This was fixed in 80c2e9657f2 (bisect--helper: report
actual bisect_state() argument on error, 2022-01-18), but the error
message still talks about `bisect--helper`, which is an implementation
detail that should not concern end users.

Fix that, and add a regression test to ensure that the intended form of
the error message.
