Monitor chain swap addresses (#322)

* Check chain swap addresses for unspent outputs

* Monitoring expired swaps up to 4320 blocks after expiration

* Refactor chain swap monitoring

* Handle the error to prevent the loop exiting

* Add RefundPending state

* Check if RefundPendingbefore setting to Refundable

* Use script_get_balance to determine spent state

* Use unconfirmed balance to check if RefundPending should be reset to Refundable
