[new-owner-report] fix args to make-payment->invoices-table

It should receive 1 arg instead of 2.

guile-2.2 allows internal defines to be called with a higher number of
args.  This may be a guile bug.  Follow-up tracking at
https://lists.gnu.org/archive/html/bug-guile/2019-12/msg00011.html

guile-2.0 (IMHO correctly) does not allow this invalid call.
