Merge #278: Implement lockunspent method and test

045b25e Format code (GideonBature)
98ea4be Implement lockunspent method and test (GideonBature)

Pull request description:

  The JSON-RPC method `lockunspent` does return a type. We want to test this to catch any changes in behavior in future Core versions.

  This PR adds a client function that errors if the return value is anything other than the type it returns, along with an integration test that calls this function.

  Ref: [#116](#116)
