SomberNight fe5cb09e05 wallet_db: convert PaymentInfo amounts from 0 to None
When creating a "zero-amount" payment request, currently we save a PaymentInfo with a "None" amount.
I think there were a few releases in 2023 that saved PaymentInfos with a `0` amount instead. This was changed in #8659 [0], but as said there [1], a DB upgrade was not done.
Now an assert added in [2] is failing due to this inconsistency, for affected old wallets.
- I think to trigger that, one needs a wallet that has a payment request (with a `0` amount) created around that time, which is still unpaid.

This patch tries to restore consistency by enforcing None amounts.
