Merge #13275: Qt: use [default wallet] as name for wallet with no name

2885c13 Qt: use [default wallet] as name for wallet with no name (Jonas Schnelli)

Pull request description:

  Loading a wallet from a state where only the default wallet was active results in using an empty string for the initial/default wallet name.

  This is a GUI only quick-fix that overrides wallet(s) with name "" to "[default wallet]". Does not affect `getwalletinfo` or `listwallets`.

  Also, unsure if it should be fixed at a deeper level and if – instead of [default wallet] – it should use `wallet.dat` (the filename of the default wallet).
