Unfortunately, loading the migration code also reloads some Spree models
which causes errors later on. Another spec was failing with:
1) full-page cart viewing the cart when a product is soft-deleted shows the cart without errors
Failure/Error: variant.instance_variable_set :@hub, @hub
FrozenError:
can't modify frozen NilClass: nil
# ./lib/open_food_network/scope_variant_to_hub.rb:12:in `instance_variable_set'
The command to reproduce was:
rspec ./spec/features/consumer/shopping/cart_spec.rb[1:1:3:1]\
./spec/migrations/migrate_enterprise_fee_tax_amounts_spec.rb[1:1:1:1] --seed 0
I couldn't find a quick solution to make the migration not use app code.
Since the migration is a historical record now, it doesn't need repeated
testing.
