After deleting an order item the product is not restocked

[magenta-cuda]

Describe the bug
After an order item is deleted using the "Edit order" page the corresponding product is not restocked.

To Reproduce
Steps to reproduce the behavior:

1. Place an order for a simple product with stock management enabled and pay by check.
2. Using the "Edit order" page delete the order item - click on the x.

Expected behavior
The product should be restocked.

Isolating the problem (mark completed items with an [x]):

• I have deactivated other plugins and confirmed this bug occurs when only Classic Commerce plugin is active.
• This bug happens with the Storefront by Automattic theme active.
• I can reproduce this bug consistently using the steps above - 3 times, twice with other plugins active once with only CC active.

The solution to this bug can be found in issue 337 #337

As an alternative to deleting the order item the store owner may want to consider clicking the refund button and doing a total refund on the order item instead.
