Merge all IOU data in one swoop

Details

Cleaning up the report IOU fetching logic so that we can use mergeCollection on the report and report ious that we get back. Eventually we should make the server send this information, but this should work OK for now. I'm not really following how to use curl to set up the IOUs. But the PR should work for adding this to the report data I think.

Not sure if there is another issue to handle the realtime event pusher event, but not including it here.

Tests

1. Create a new IOU transaction via

CreateIOUTransaction
authToken: <auth token>
debtorEmail: <email of user you want to request payment from>
currency: USD
comment: 'test'
amount: 299

2. Open E.cash as the user (same authToken that you just used)
3. Verify that there is a hasOutstandingIOU & iouReportID fields in the Onyx data for the report
   
4. Run the next command to mark it as paid

PayIOU
authToken: <auth token of the payee> // must sign in as the "debtor"
reportID: <IOU Report ID> 
paymentMethodType: 'Venmo'

5. Refresh the page
6. Verify that the report data shows hasOutstandingIOU=false
