Reproduce the Crashing app after Tauri upgrade

[tomaszantas]

thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: "Connection error: transport error caused by:\ntransport error caused by:\nerror trying to connect: tcp connect error: Connection refused (os error 61) caused by:\ntcp connect error: Connection refused (os error 61) caused by:\nConnection refused (os error 61)"', applications/launchpad/backend/src/api/wallet_api.rs:70:84

do not 'unwrap' - handle the error gracefully and return it to the frontend, so it know it should wait

waiting for tauri upgrade #324 the crash might be related to production build only

Solved with #351
