Investigate robustness of redeem request step.

[gianfra-t]

Context

It was observed that the app was stuck at the redeem request step, with error {"type":"recoverable","message":"Error: Failed to request redeem"}}.

Nevertheless, the request was done properly and the transaction went through. It is unclear why the app returned this error and why it couldn't recover.

To Do

Analyze that part of the code (here and here for example) and check what can be improved such that if any generic submission error arises, we still can recover or be sure that the extrinsic did fail, and not just the response of submitting it.

@pendulum-chain/product this bug has been observed or at least documented only once. It is important as it happens at the redeem stage of the flow and funds are on the ephemeral account. Offramp can be recovered easily by executing the dumped transactions, but it is irrecoverable if those are lost.

@gianfra-t what's the status here? i dont see a linked PR to it as this is in review

[gianfra-t]

Good catch, we kept the conversation internal. We couldn't find the issue since the app should reload in case of a failure like this, and not "get stuck". It also didn't happen again.

I think the conclusion was to do nothing regarding this, so we could close the issue. C.C. @pendulum-chain/devs

Yes, I think it's hard to debug so a wont-fix.
