Mint: Can `clnrest.py` pay the same invoice twice?

[callebtc]

Word on the street is that CLN's/v1/pay does not return an error if you try to pay the same invoice again. Before attempting a payment, we should first check if the payment already exists and only attempt a payment if it doesn't.

Are there any instances where the mint could attempt to pay an invoice again?
