UPS carrier doesn't allow empty company name in from_address

[vassalloandrea]

Problem

UPS carrier doesn't allow an empty company name in the from_address object which is the stock_location object serialized.
This happens because the gem uses the same serializer for the shipment and the stock location.

solidus_easypost/app/decorators/models/solidus_easypost/spree/address_decorator.rb

Line 16 in 3afa657

attributes[:company] = company if respond_to?(:company)

The stock location hasn't the company attribute and it isn't sent to Easypost.

How to replicate

Try to ship a shipment with a UPS shipping method.

Possible solution

Use different easypost_address method for the stock location using the name as the company.
