Function parameters initialized with a class constant throw an exception

Hello,

In the following code :
```php
init([
'debug' => true,
'includePaths' => [
__DIR__ . '/../src',
'excludePaths' => [
__DIR__ . '/../tests'
]
]
]);
?>

"save is mocking"]);
}

protected function tearDown()
{
test::clean(); // remove all registered test doubles
}
}
```

when we launch the test we get the following exception :

```
PHPUnit 5.7.3 by Sebastian Bergmann and contributors.

Starting test 'AspectMockTest::testDouble'.

Do you have any solution or fix to help us please ?

Bắt đầu bằng cách chạy tests/AspectMockTest.php với bootstrap và ví dụ UserModel.php từ issue. Truy vết lỗi qua BeforeMockTransformer.php và parser-reflection stack của goaop, đặc biệt là NodeExpressionResolver và ReflectionEngine. Hoàn tất khi ví dụ testDouble chạy được mà không gặp PDO locator exception, đồng thời vẫn giữ nguyên tham số mặc định là hằng số lớp.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
