Reverse Swap: Claiming doesn't work

[kilrau]

First observed on iOS, but probably not specific to iOS as we had a user in our TG group reporting what looks like the same for Firefox on Android: Web App says it's "Claiming transaction now..." but it just doesn't work and can't be fixed via refresh, navigating back in etc. It just doesn't claim. It's a rare edge case, we have 2 reports in total so far and need user's help to submit logs to debug, hence: https://github.com/BoltzExchange/boltz-web-app/pull/576
