NullsafeOperatorRector tries to fix code that should be left alone. Example below.

Minimal PHP Code Causing Issue

public function getValue(\Entity $entity)
{
    $value = $this->baseField->getValue($entity);

    if ($value === null) {
        return null;
    }

    return $this->baseField->select($value);
}

Current Behaviour

public function getValue(\Entity $entity)
{
    return $this->baseField->getValue($entity)?->select($value);
}

Expected Behaviour

Should be left as is.
