Added failing test for issue: AccessType("public_method") ignored when deserializing to XmlList, etc.

XmlDeserializationVisitor::visitProperty uses reflection to set properties unless none of xmlAttribute, xmlValue, xmlCollection are set. For any remaining properties, reflection will only be used if metadata->setter is null. The latter logic seems more desirable for all cases.

This is presumably a bug? I can't see any reason the following configuration should not be using setItems when deserializing from XML:

    class Order {
        /**
         * @Type("ArrayCollection<Item>")
         * @XmlList(entry = "item", inline = true)
         * @AccessType("public_method")
         */
        private $items;

        public function setItems($items){
            $this->items = $items;
            //Do something else
        }
    }

I ran into this when attempting to make sure my Items were aware of my Orders, as Item was the owner of a Doctrine association. Attached is a failing test.
