[bisq-network/bisq] Inconsistent wallet sizes (#2797)

[Oscar Guindzberg]

Status report

@yourwpguy sent his original bisq data dir in private and I could reproduce the bug.

bitcoinj wallet is corrupted.

Exception at startup:
org.bitcoinj.wallet.UnreadableWalletException: Wallet contained duplicate transaction 1debca5f5f8778497a538e7959c6b5280b1862c14c3eb1c8597bbc2249f871ea

This tx https://blockstream.info/tx/1debca5f5f8778497a538e7959c6b5280b1862c14c3eb1c8597bbc2249f871ea is duplicated in the wallet file.

I don't know how the bitcoinj wallet file ended up being corrupted.

After the user has followed the steps I wrote on my previous comment, he does not get an error on bisq startup anymore.

User says:

The corrupted wallet or error appeared after a trade, where the scammer was blocked:
I was selling BTC as taker.
Error message:
An error occurred at task: CheckIfPeerIsBanned
Other trader is banned by his trading account data.
Trade state: TAKER_FEE_PUBLISHED
