Prepare fixture data for account sync tests (#493)

* Rename account balance field for clarity

`original_balance` and `original_currency` may infer that these values are "original" to the account.  In reality, they represent the "current" balance and currency on the account.

* Prepare fixture data for account sync testing

* Update to new field

* Fix conflicts

* Remove local schema change
