vue-storefront

#2008

@NataliaTepluhina - please add this to the docs as well:

Starting with Vue Storefront v1.6 we changed the default order-placing behaviour. Currently the `config.orders.directBackendSync` is set to `true` be default. With this option enabled - if the user is online, Vue Storefront tries to pass the order immediately and synchronously (waiting for result) to the eCommerce backend. This option gives immediate and direct feedback to the user. If there is an app-level error (for example validation error on Magento side) user will be notified immediately. If there is transmission issue (no connection, servers are down etc) the order is being put into queue (as it was prior to 1.6). If `config.orders.directBackendSync` is set to false - then the legacy behaviour with queuing all the orders is being used. With `directBackendSync` set to true we do have access to the server confirmation (with backend orderId) in `store.state.order.last_order_confirmation`
