Currently when payment is processed through the payment link by
public user then there is no details of partner(email, country etc..)
so due to that some payment provider(paypal, stripe etc.) produce
the traceback on public payment
so when generating link for the payment pass the partner on link so
where payment is processed by public user then it will get the customer
of the record as partner, so on behalf of the customer the payment is
processed.
