0058244: qtyOffer is set to 0 when the limit is reached in a Pack discount with multiple instances

Description

When reaching the limit of a Pack discount with multiple instances configured, the discount engine does not calculate the qtyOffer of each line correctly.

Before reaching the limit, it calculates correctly. However, once the limit is reached, it sets the qtyOffer to 0.

Steps To Reproduce

PRECONDITION (BACKOFFICE):
- Go to the Discount & Promotions window
- Open the Test Coupon discount
- Set the Discount/Promotion Type to 'Pack'
- Set the Currency to 'EUR' and the Discount/Promotion Price to 10
- Set the Limit Multiple Instances per Order field to true
- Set the Limit of Instances per Order field to '2'
- Set the Included Products field to 'Only those defined'
- Go to the Products subtab below
- Add the Avalanche Transceiver product with a quantity of 1
- Add the Headlamp Ultralight product with a quantity of 2

TEST IN POS:
- Use a Standard Terminal (VBS-2).
- Add the Avalanche Transceiver product 1 times
- Add the Headlamp Ultralight product 2 times
- Check the console
   * Open the console (Press F12)
   * Print the lines (OB.App.State.getState().Ticket.lines)
   * In each line object, open its promotions and check the 'qtyOffer' value
     ( Can use this line: OB.App.State.getState().Ticket.lines.forEach(l=>console.log(l.promotions)) )
   * The first line has a qtyOffer of 1, and the second has a qtyOffer of 2
- Add again the Avalanche Transceiver product 1 times (Total: 2 x Avalanche Transceiver)
- Add again the Headlamp Ultralight product 2 times (Total: 4 x Avalanche Transceiver)
- Note that we reach the limit configured in the backoffice: 'Limit of Instances per Order'
- Check the console
   * Open the console
   * Print the lines
   * In each line object, open its promotions and check the 'qtyOffer' value
   * The first line has a qtyOffer of 0, and the second has a qtyOffer of 0
