Merge #11250: Bump wallet version to 159900 and remove the usehd option

713a92073 Remove usehd option and warn when it is used (Andrew Chow)
d4c18f733 Bump wallet version number to 159900 (Andrew Chow)

Pull request description:

  Bump the wallet version number to 159900 so that new wallets made without a default key will no longer work on previous versions at all. Also remove the `usehd` option to avoid weird interaction with wallet version numbers and HD-ness of wallets.
