rails: Scopes defined on Abstract ActiveRecord classes are missing table names when called from subclasses

If a scope is defined on an abstract active record class, when it is called by one of its subclasses the sql generated is missing a table name.

class AbstractCompany < ActiveRecord::Base
  self.abstract_class = true

  scope :abstract_company_scope, ->{ order('id') }
end

class Company < AbstractCompany
end

Company.abstract_company_scope #=> ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: : SELECT  "".* FROM ""   ORDER BY id LIMIT 1
