Depending on the invoices in stripe there could be some nil values for
things so we need to account for those in this job or an exception will
be thrown causing the job to fail.
* FIX: Include one-time purchases in campaign total
On the subscription banner that shows on the top of the forum it shows
the total amount raised toward a goal. But the amount shown was not
including one-time purchases. It was only showing subscriptions.
This change updates the sync with stripe logic so that it also includes
one-time purchases.
