Don't show CJ broadcasted if wallet had no input in the round

[turbolay]

Fixes #9544

The issue is that the round success, just we had no input in it because we lost internet before confirming inputs (so we didnt make the round to fail). Because the ViewModel is only checking if the round failed or succeed, it will display success.

The solution is to check if we had any input in the round, and if no pass the information in the RoundEnded object.
These are the minimum changes possible to fix the issue, if anyone has any idea please express it.

Really annoying to test, you have to close the lid (make computer to go to sleep) during last minute of InputsRegPhase then wait 5 minutes then pray for the round to be successful.

Can we do it without adding business logic?

Naive ideas:

• Change the message in the music box to be correct?
• Just indicate failure in the UI?
• Any other idea that is not touching the business but fixing this edge case UI problem?

I followed your advice @molnard and now throws instead of the complexity I had before.
I tested this code and it works great, the only issue is that in the logs there is:
Round (ded775054098d3fa9652626fc79ea774b16fe0dbc4ce0dbcd17909821edb6233): Broadcasted. Coinjoin TxId: (Not available)
But I don't think this is a problem.

Sorry, I did something wrong here with git. I've just synced with your branch and this happened. I don't know how to fix it, can you take a look - it might be easier to remove my last commit as you are the owner of the branch.

I removed your commit, I just resetted branch and forced push
