dca3f36 [PropertyAccess] Use ArrayAdapter in debug mode

PHPUnit 5.3 doesn't have the forward compatibility layer for PHPUnit 6 so that `PHPUnit\Framework\TestCase` can be used instead of `PHPUnit_Framework_TestCase`.
This generates an error when upgrading to Symfony 3.2.5 without forcing the `SYMFONY_PHPUNIT_VERSION` const:

```
Class 'PHPUnit\Framework\TestCase' not found in vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Test/KernelTestCase.php on line 25
```

This was introduced by c9684ad in 3.2.5
