Spree 2.0 keeps shipping fee adjustments open unless they are manually
closed. But open adjustments cannot be edited.
To preserve updates, like changing the amount of the shipping fee
we close the adjustment first.
Note that, as explained in
https://apidock.com/rails/v3.2.13/ActiveRecord/Relation/delete, `delete` does
not trigger callbacks and so it skips the products cache logic.
If we still want to avoid instantiating the AR object, we need to explicitly
call that logic for the cache to be up-to-date.
The admin variants controller create action is adapted (same as in the admin ProductsController). This is necessary because variant.on_hand and on_demand cannot be mass assigned on creation in v2, see VariantStock for more details.
For now we are hiding the new stock management page that comes in spree v2 as we don't need the complexity added by the management of stock per stock location (only one stock location in ofn v2 for now)
This separates logic for bang and non-bang versions of
Spree::Order#next.
The different conditions used in both methods (state == "completed" vs
order.completed?) have implications in whether a transition is attempted
or not.
Spree made that scope default so that we don't need to define or call
it. There might be cases in which we were showing deleted variants and
now we are not, but I have not idea how to find them.

This keeps the override of Spree's model leaner. More importantly, it
prepares us for using `destroy` instead of `delete`.
In the past, `Product#delete` soft-deleted the product, but didn't
delete the variants. When we use `Product#destroy` to soft-delete the
product, it will also call destroy on the variants. If the model doesn't
allow the deletion of the last variant, it will fail. So when a product
is deleted we want to allow the deletion of all variants. But the user
should not be allowed to delete the last variant. That's why I'm moving
the check to the controller level.

Spree changed their way of soft-deleting products, variants and
some other models. `#destroy` is now soft-deleting and replaces
`#delete`.
This commit considers only products. Variants will follow in another
commit. The other models can be ignored, because we don't call `delete`
on them.
