Merge #276: Implement importwallet method and test

c62b4d2 Implement importwallet method and test (GideonBature)

Pull request description:

  The JSON-RPC method `importwallet` does not return anything. 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 `null`, along with an integration test that calls this function.

  Ref: [#116](#116)
