tests: add optional output when wheel is missing

If the `wheel` package isn't installed, pip will emit a warning
on stderr complaining about that. Alternatively, we could
redirect stderr to stdout and swallow the warning. But I like
tests having visibility of warnings, as it helps keep us honest
regarding edge cases.
