Tests: Make assertCapturedSuccess check stderr is empty again (#1087)

`assertCapturedSuccess` used to check that `stderr` was empty, until:
https://github.com/heroku/heroku-buildpack-python/commit/797652a75d69a1fece96a26bf4514fe9e9e1c020#diff-65c067a6f0a3aef292fb54ec21a1fe8cR98

Adding back the assertion exposes some new bugs, which I'll fix in
later PRs. In the meantime affected tests have been adjusted to use
a new `assertCapturedSuccessWithStdErr`.

The test harness output for the failing case has also been improved,
to ease debugging.

Closes @W-7918492@.
