Merge #14631: [tests] Move deterministic address import to setup_nodes

3fd7e76f6d [tests] Move deterministic address import to setup_nodes (John Newbery)

Pull request description:

  This requires a small changes to a few tests, but means that
  deterministic addresses will always be imported (unless setup_nodes
  behaviour is explicitly overridden).

  Tidies up the way we import deterministic addresses, requested in review comment here: https://github.com/bitcoin/bitcoin/pull/14468#discussion_r225594586.
