preventOverlapping not working on closures

[g19i85g]

Crunz version: 2.2.0

PHP version: 7.3.19

Description
The method preventOverlapping() does not work.

How to reproduce
Create a long running task and let it run every minute.
After a few minutes you can see that the task runs several times.

use Crunz\Schedule;

$schedule = new Schedule();
$task = $schedule->run(
    static function () {
        sleep(500);

        return true;
    }
);
$task->everyMinute()
     ->preventOverlapping();

return $schedule;

Additional context
I found out that the method \Crunz\Event::lockKey() creates a new key every time I start the run command.

public function serialize()
    {
        ...
        $this->reference = spl_object_hash($this->closure);
       ...
        $ret = \serialize(array(
            ...
             'self' => $this->reference,
         ));
       ...
    }

I suppose the part of the method \Opis\Closure\SerializableClosure::serialize() is the cause.

Hello, after #313 you can specify lockKey yourself, that should resolve the problem.

Yes, that's true but from my point of view this is more of a workaround. Maybe you could make it mandatory to hand over the key when using closures.

Fixed by #326, thanks @g19i85g.
