gui: Fix duplicate wallet showing up

Browse source 
The slot BitcoinGUI::addWallet can be invoked twice for the same
WalletModel due to a concurrent wallet being loaded after the first `connect()`:

```cpp
 connect(wallet_controller, &WalletController::walletAdded, this, &BitcoinGUI::addWallet);
 connect(wallet_controller, &WalletController::walletRemoved, this, &BitcoinGUI::removeWallet);

 for (WalletModel* wallet_model : m_wallet_controller->getOpenWallets()) {
     addWallet(wallet_model);
```
