Elect a payment method on account to be the 'default' payment method recruited by that account's subscriptions

DefaultPaymentMethodElection.js

BillForward.Account.getByID('ACC-81674A80-3B2D-4327-8C24-994720BA')
.then(function(account) {
	// you might want to take a peek at the account
	// console.log(account.toString());
	
	// get relevant payment method:
	var paymentMethod =_.findWhere(account.paymentMethods, {'gateway': 'stripe'});
	
	// the SDK seems to have an unserialization problem; we need to manually tell JavaScript that this JSON is a BillForward.PaymentMethod:
	_paymentMethod = new BillForward.PaymentMethod(paymentMethod);
	
	// set as default payment method
	_paymentMethod.defaultPaymentMethod = true;
	// PUT changes to API
	return _paymentMethod.save();
})
.done();
