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 ?

Start by running tests/AspectMockTest.php with the bootstrap and UserModel.php example from the issue. Trace the failure through BeforeMockTransformer.php and the goaop parser-reflection stack, especially NodeExpressionResolver and ReflectionEngine. Done means the testDouble example runs without the PDO locator exception while preserving the class-constant default parameter.
