[feature]: Expiry AMP invoice even though they have settled sub invoices.

[ziggie1984]

Currently we do not expiry recurring AMP invoice when they have at least one settled sub invoice. However that means that any AMP invoice with this conditions stays OPEN forever and can therefore accept payments forever. This might not be practical for bookkeeping reasons if we cannot rely on a final state of an invoice. Hence we should nonetheless expiry the invoice and move it into a state which will not accept more payments.

What should done here as well is to refactor the whole setID AMP HTLC invoice fetching.
