this logic here means that anytime we do a wallet match on rpc debug console, it will not find the wallet unless it has no `.dat` extension: 3dba3c3#diff-8c9d79ba40bf702f01685008550ac100R491

This also means you can load two wallets(eg `wallet.dat` and `wallet`), and they will look the same in the drop down selector.

imo if we're supporting arbitrary filename extensions we should just display the entire name

CAmount WalletModel::getBalance(const CCoinControl *coinControl) const
{
    if (coinControl)
    {
        return wallet->GetAvailableBalance(coinControl);
    }
    return wallet->GetBalance();
}
