tests: add --testrunner flag so that column tests dont fail on startup

We added a startup panic to prevent users from running as debug mode,
our tests are also hitting this. Add a new --testrunner flag which
skips this check. We want this separate from the --debug flag so that
the tests have a more consistent runtime environment.
