`new Reflectionproperty($scope, $propName)` keeps a reference to the zend_property_info of $propName declared in $scope. In getRawValue() and related methods, we use this reference to check whether the property is hooked. Calling `new ReflectionProperty($scope, $propName)->getRawValue($object)` is equivalent to the expression $object->$propName from scope $scope (except that it bypasses hooks), and thus may access an overridden property (unless the original is private). This property may have hooks and different flags. Here I fetch the effective property info before checking for hooks and property flags. Fixes GH-17713 Closes GH-17714
