Cancel AuthorizeNet ARB fails

Cancel shows as canceled in the site but leaves errors in the logs and doesn't cancel the subscription with ARB.

The culprit is referencing a variable that should be from an object($order_id to $order->order_id). Also the second paramter should accept a value(&$fee to $fee).

file: uc_recurring_hosted.module
function: function uc_recurring_hosted_authorizenet_arb_cancel

Fixes:
line 454: function uc_recurring_hosted_authorizenet_arb_cancel($order, $fee) {
line 481: if (!empty($order->order_id)) {
line 482: uc_order_comment_save($order->order_id, 0, t('Authorize.Net: Subscription @subscription_id cancellation failed.
@error - @text', array('@subscription_id' => $subscription_id, '@error' => $data['code'], '@text' => $data['text'])), 'admin');
line 487: uc_order_comment_save($order->order_id, 0, t('Authorize.Net: Subscription @subscription_id cancelled.', array('@subscription_id' => $subscription_id)), 'admin');

I tested this and I get no errors logged and ARB does cancel the subscription.
