[CartBundle] Removed redundant cart refresh

Cart refresh is already handled by RefreshCartListener which subscribes to SyliusCartEvents::CART_CHANGE. That event is already dispatched along other cart-changing events such as SyliusCartEvents::ITEM_REMOVE_INITIALIZE and therefore refreshCart() is redundant and should be removed from CartListener
