[Bug] A claimable payout may be not displayed

[Leouarz]

Hey,

If for the same era there are multiple claimable payouts for the same user and the first one has been claimed, the next one won't be shown in the modal.

The issue comes from this piece of code : https://github.com/polkadot-cloud/polkadot-staking-dashboard/blob/main/src/contexts/Payouts/index.tsx#L253-L303

Especially in this line, even if the first unclaimed payout is zero, j should be incremented and the next validator should be checked.

Hopefully I understood the code correctly, I can also open a PR if necessary.
Don't hesitate if you need more info.
