If no event is found, LatestRoundRequested should return zero values, not an error. An error should only be returned if an actual error occurred during execution, e.g. because there was an error querying the blockchain or the database.

As an optimization, this function may also return zero values, if no RoundRequested event has been emitted after the latest NewTransmission event.
