Configurable stock status is not correct when using custom stock (MSI)

This PR fix when MSI enabled to product ,the configurable product status must be updated when a child's product status is changed.

create new source in admin > store > sources, i.e : source A
create new stock in admin > store > stock, i.e : custom stock
assign source A to Custom stock, and also assign custom stock to main website
create new configurable product, i.e : test product
- add simple product to the configurable product in configuration tab
- assign simple product to source A
- fill quantity, i.e : 1
and save new created configurable product. (in this step the configurable product stock = In Stock)
now change the simple product :
- Source Item Status : from In Stock to Out Of Stock
- Qty : from 1 to 0
- save simple product
check configurable product (the stock status is still In Stock, it must be Out Of Stock)
