If you place ASF models in their own module, for example Salesforce::Account, Salesforce::Contact, etc, interesting
things can occur:

>> Salesforce::Account.find('00100000003ShySAAS').contacts.size
ActiveSalesforce::ASFError: INVALID_FIELD: No such column 'account_id' on entity 'Contact'. If you are attempting to
use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe
call for the appropriate names.

Strangely enough, just calling contacts (basically, Contact.find_all_by_account_id id) works, but
ActiveSalesforce::ResultArray#size breaks!
