qt: Fix WalletControllerActivity progress dialog title

The WalletControllerActivity progress dialog had title of "Bitcoin-Qt".
The window title for opening wallet window should be "Open Wallet",
for creating wallet window should be "Create Wallet", and for the window
that is displayed when wallets are being loaded at startup should be
"Load Wallets". This PR fixes that.
