fadf31e wallet: Display non-HD error on first run (MarcoFalke)

Pull request description:

  On current master a fresh wallet created with `-usehd=0` is silently created as HD wallet.
  An error should be displayed on the first run.

  Also, this restores a test that was removed in c22a53c

  Fixes: #11313

Tree-SHA512: 226a4129984324f88a431c7e2726383f6841711f0227d8e9f5b4f89d4bb9f2b8e922e6cf0a6f91d6efa747d139543a236b9f29326fc5d1e5d6f1dea2465d9b85
