Fix CustomerAddress.all returning no results

Previously, when fetching `all` on CustomerAddress it would return an
empty array. Two issues (Shopify#970, Shopify#1018) were opened outlining the problem.

Initial attempt was to override `json_response_body_name` which worked
for fetching arrays of results. It doesn't work for fetching individual
results though.

I wound up overriding `create_instances_from_response` for
CustomerAddress. It isn't ideal but it does seem to behave correctly.

Assertions have been added to the the tests as well.
