5b9b484 qml: Show Add Wallet in WalletBadge if none are found (johnny9)
7af55d5 qml: Hide tabs and show Select Wallet if no wallet is loaded (johnny9)

Pull request description:

  In addition to changing the component in the top left corner, the navigation tabs will be hidden if no wallet is loaded until a wallet is created/selected.
