Throw and null coalesce combination

```php
$this->brokerModel->updateFromInput($seller->getBroker(), $input->broker
    ?? throw new \App\Exception\SellerTypeChange());
``` 
is replaced with
```php
$this->brokerModel->updateFromInput($seller->getBroker(), $input->broker
    ??
throw new \App\Exception\SellerTypeChange());
```
