Fix file name extension not stored

[dswtech]

FIle extension not saved when using create method

$attachment = $this->create(request()->file('thumbnail_image'), [
            'disk' => 'thumbnail',
            'type' => 'thumbnail',
            'title' => 'This is File Title',
        ]);

Kayaknya perlu dicek mas, kalau udah ada extensionnya langsung eksekusi, kalo nggak ada dia pake client extension. Soalnya nanti ngerubah kodingan di beberapa tempat..
