cefb399e2 gui: Use AutoConnection for WalletModel::unload signal (João Barbosa)

Pull request description:

  This PR is a subset of the work done in the context of #13100. This change consists in extracting from the application class the code that manages the wallet models.

  The role of the `WalletController` instance is to coordinate wallet operations and the window.
