fix: RecordCustomAudit listener

[Pr3d4dor]

This pull request fixes this problem:

OwenIt\Auditing\Listeners\RecordCustomAudit::handle(): Argument #1 ($model) must be of type OwenIt\Auditing\Contracts\Auditable, OwenIt\Auditing\Events\AuditCustom given, called in /mnt/c/Users/bine/Documents/mapos-laravel/vendor/laravel/framework/src/Illuminate/Events/Dispatcher.php on line 478

I'm assuming that fixing these tests also makes sense as well as correcting the listener

@willpower232 There is a strange behavior, maybe there is a bug in the Laravel core.

This does not work:

Event::dispatch(AuditCustom::class, [$this]);

But this works:

Event::dispatch(new AuditCustom($this));
