Thread 'main' panic during wallet sweep

[DagitUser69]

When issuing a sweep command from the CLI wallet sometimes there is a thread 'main' panic and the wallet halts and quits. I have noticed this when there is more UTXOs in the wallet.

When this issue occurs some of the UTXO's are successfully swept while still leaving some UTXO's remaining. re-launching the wallet and re-running sweep command will sweep the remaining UTXO's.

I have attached a screenshot of the sweep when thread main panic occurs.

Will check it in next dev branch, it is too late for v0.3.15 already as we are close to release it.

@DagitUser69 That bug happens because some of the data collected during the summary information process wasn't handled properly, leading to crashes during sanity checks when sweeping large sets of UTXOs. It was addressed in our latest release: https://github.com/spectre-project/rusty-spectre/releases/tag/v0.3.16
