Remove product from cart is not updating projection

[SamAllen83]

Steps to reproduce

1. Import attached postman collection
2. Run CQRS_Flow/Java/event-sourcing-esdb-aggregates or CQRS_Flow/Java/event-sourcing-esdb-simple application locally
3. Send 1. Open Shopping Cart Postman request. This will store ETag and Location for future requests.
4. Send 2. Add Product To Cart Postman request. This will update stored ETag for future requests.
5. Send 3. Get Cart By Id Postman request. This will store productId and unitPrice for future requests.
   • Notice Shopping Cart has 1 product in productItems
6. Send 4. Remove Product From Cart Postman request. This will update stored ETag for future requests.
7. Send 3. Get Cart By Id Postman request.

Expected Result

• Shopping Cart should have 0 products in productItems

Actual Result

• Shopping Cart has 1 product in productItems

Developer Note: I will submit a PR to fix. The issue is this line of code:

view.getProductItems().remove(existingProductItem);

Should be

view.getProductItems().remove(existingProductItem.get());

existingProductItem is of type 'Optional', need to call .get() to get ShoppingCartDetailsProductItem.
