Before this commit:
1. We were checking if the rewards were in the SO even if it was 'next_order'
program.
2. We were deducing the rewards quantity for 'next_order' program when checking
if we had enough products to meet the program requirements.
Now:
1. We don't verify if the reward is on the SO if the program is 'next_order'
2. We don't deduce reward quantity when checking if enough products to meet the
program requirements if the program is 'next_order'
