[Forwardport] #4942 and bundle checkbox bug

Original Pull Request

#15905

This fixes two bugs in relation to bundled products and a customer editing their selections in the cart.

Description

When a bundle item was edited after being in the cart, it was no different than loading the original product. There are two aspects to the fix:

• Updating the JSON config to show the new quantities and selections
• Adding selection array matching for checkboxes.

Fixed Issues (if relevant)

1. On editing a Bundle product from shopping cart the user defined quantities of the options are overwritten #4942: On editing a Bundle product from shopping cart the user defined quantities of the options are overwritten

Manual testing scenarios

1. Locate a bundled item with checkboxes
2. Add that bundled item to the cart (with at least some checkboxes checked)
3. Edit the item in the cart.
4. Ensure that all items are checked and that the specified quantities match.
