[CartBundle] Removed redundant cart refresh

Cart refresh is 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
