Merge #11307: wallet: Display non-HD error on first run

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
