Call to function runLightweightCron() on null in SchedulerCommands->cron()

The new scheduler cron command for Drush 9 has the following error:

Error: Call to a member function runLightweightCron() on null
in Drupal\scheduler\Commands\SchedulerCommands->cron()
(line 59 of scheduler/src/Commands/SchedulerCommands.php)

The code was introduced in #2951072: Provide Scheduler drush commands for Drush 9 but has a simple typo on the line

$this->manager->runLightweightCron($options);

which should be

$this->schedulerManager->runLightweightCron($options);
