Merge #300: descriptors: require that an origin be set for the keys.

1cd61c9236b7ecacd39787a84edfcacaec024673 descriptors: require that an origin be set for the keys. (Antoine Poinsot)

Pull request description:

  It would be possible for users to create a descriptor with xpubs without an origin set. In fact, not many are used to origins and it's a very likely mistake. Signers need this information in order to be able to sign. So they could potentially create a wallet and potentially never be able to sign for one or multiple keys.

  Fix this by requiring an origin for all keys in the descriptor.

  Fixes #290.
