Since https://github.com/ooni/probe-cli/pull/527, if an experiment returns an error, the corresponding measurement is not submitted since the semantics of returning an error is that something fundamental went wrong (e.g., we could not parse the input URL). This diff ensures that all experiments only return and error when something fundamental was wrong and return nil otherwise. Reference issue: https://github.com/ooni/probe/issues/1808.
