Subject: [PATCH] swap: add a recovery process for AwaitFeeInvoice

`AwaitFeeInvoice`state to hang in case of state mismatch with peer.
https://github.com/ElementsProject/peerswap/issues/290

To eliminate the persistence of uncompleted swaps,
execute "cancel" if recovery by restart
is executed in `AwaitFeeInvoice` state.
