Unable to edit quantity of items in new order

[bvalentino]

The line_items.js.coffee is overriden in spree-products-assembly and it has not been updated along with the spree 2.3.x. Hence, some issues arise when trying to edit a new order.

When clicking the edit button in a line item row, it should show the input field for the quantity, which is not happening. Also, when pressing the Ok button after editing, it is triggering a reload of the order.

Steps to reproduce

1- Spree store version 2.3.4 (fresh installed).
2- Check that editing capabilities of new order quantities is working.
3- Add spree-product-assembly gem and install: rails g spree_product_assembly:install
4- Note how editing of new order quantities stopped working.
