0030157: One or two payment details when paying an invoice when invoice's amount is higher that order's amount

Description

Depending on the way you create an invoice from an order where the invoice's amount is higher that order's amount, the system creates 1 or 2 payment details when paying the invoice.

If the quantity is the same, but the invoice's unit price is lower, the system creates 2 payment details.
If the quantity is lower, but the invoice's unit price is the same, the system creates 1 payment detail.

Note that the payment detail amounts are OK in both scenarios, however I think the system should behave the same way regardless the flow

Steps To Reproduce

Create a Sales Order:
  BP: Alimentos y supermercados
  Invoice Terms: Immediate
Create 1 line:
  Qty: 10
  Product: Agua sin gas
  Price: 1.53
Book the order

Create a Sales Invoice:
  BP: Alimentos y supermercados
Press Create Lines From and select the 2 lines from the previous order
Go to Lines tab, and edit the agua sin gas line. Change qty to 5
Complete the invoice.
Add a new payment for the full amount.
Go the Payment and verify we have 1 payment detail

Proposed Solution

Study if this behavior makes sense.
Ideally two flows should create the same result
