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
{
    return wallet->GetUnconfirmedBalance();
}
CAmount WalletModel::getImmatureBalance() const
{
    return wallet->GetImmatureBalance();
}
bool WalletModel::haveWatchOnly() const
{
    return fHaveWatchOnly;
}
CAmount WalletModel::getWatchBalance() const
{
    return wallet->GetWatchOnlyBalance();
}
CAmount WalletModel::getWatchUnconfirmedBalance() const
{
    return wallet->GetUnconfirmedWatchOnlyBalance();
}
CAmount WalletModel::getWatchImmatureBalance() const
{
    return wallet->GetImmatureWatchOnlyBalance();
}
void WalletModel::updateStatus()
