[BUGFIX] Dont call filesystem delete with null

[Woeler]

Applications using Laravel 9 will use FlySystem 3. The delete methods of FlySystem 3 no longer allow null as an argument. The argument must be a string.

See: https://github.com/thephpleague/flysystem/blob/3.x/src/Filesystem.php#L82

This pr simply surrounds the delete call with an if statement, so it isn't called when the given argument is null. This happens when using Laravel 9 while creating a new resource using the AdvancedImage field.

I am not sure if this is being maintained anymore. For those wanting a solution without editing the vendor code, create your own class that extends AdvancedImage and use it in instead. Class looks like this:

<?php

declare(strict_types=1);

namespace App\Nova\Fields;

use Laravel\Nova\Http\Requests\NovaRequest;

class AdvancedImage extends \Ctessier\NovaAdvancedImageField\AdvancedImage
{
    protected function fillAttribute(NovaRequest $request, $requestAttribute, $model, $attribute): void
    {
        $model->{$attribute} = $model->{$attribute} ?? '';

        parent::fillAttribute($request, $requestAttribute, $model, $attribute);
    }
}
