fix tests and bump

The liquid transactions list was showing all transactions to the wallet, even when it had nothing to do with the specific crypto code (e.g sending LBTC txs in USDT, LCAD in USDT, etc). This PR fixes that.

It also uses the previously introduced checkout decimal precision fix to the Wallets screen, specifically the balance amount on wallet llist and balance change on transaction list.
