Due to a bug in ActiveRecord we need to load the tagging code in Gateway which
should have inherited it from its parent PaymentMethod.
We have to call it before loading the PaymentMethod decorator because the
tagging code won't load twice within the inheritance chain.

If the shipping_rate is not created at the time the `#after_save`'s
`#ensure_correct_adjustment` callback is executed its call to
`shipping_method.create_adjustment` won't be executed either.
As a result, the OrderUpdater wasn't able to see any adjustments related
to the shipment causing the order total to be outdated.

Match date format in spec with import date filter
Make in_stock? work for both variants and overrides by moving it from VariantStock to variant_decorator.
Add unit test for VariantStock.can_supply?
Remove rescue from products_reset_strategy in product import: if setting count_on_hand fails the import will raise a RuntimeError
Change product import's product_reset_strategy from depending on the inexistent variant.count_on_hand DB field and instead make individual calls to variant.count_on_hand= defined in VariantStock. Also, added spec to test return value of the reset method: it should return number of updated records.
Upgrade views to Spree 2 and apply overrides
