Autowiring classes containing methods with variadic method parameter throws a ReflectionException in compile process:

```
PHP Fatal error:  Uncaught ReflectionException: Internal error: Failed to retrieve the default value in /.../vendor/symfony/dependency-injection/Compiler/AutowirePass.php:437
Stack trace:
#0 /.../vendor/symfony/dependency-injection/Compiler/AutowirePass.php(437): ReflectionParameter->getDefaultValue()
#1 /.../vendor/symfony/dependency-injection/Compiler/AutowirePass.php(80): Symfony\Component\DependencyInjection\Compiler\AutowirePass::getResourceMetadataForMethod(Object(ReflectionMethod))
#2 /.../vendor/symfony/dependency-injection/Compiler/AutowirePass.php(105): Symfony\Component\DependencyInjection\Compiler\AutowirePass::createResourceForClass(Object(ReflectionClass))
symfony#3 /.../vendor/symfony/dependency-injection/Compiler/AutowirePass.php(48): Symfony\Component\DependencyInjection\Compiler\AutowirePass->completeDefinition('__controller.Sw...', Object(Symfony\Component\DependencyInjection\Definition), Array)
symfony#4 /.../vendor/symfony/dependency-injection/Compiler/Compiler in /.../vendor/symfony/dependency-injection/Compiler/AutowirePass.php on line 437
```

**Example:**
```
<?php
class FooVariadic
{
    public function bar(...$arguments)
    {
    }
}

$method = new ReflectionMethod(FooVariadic::class, 'bar');
$parameter = $method->getParameters()[0];
$parameter->getDefaultValue(); // -> ReflectionException: Internal error: Failed to retrieve the default value in ...
```
