Merge rust-bitcoin/corepc#233: Implement importprivkey and test

4b4e0840dd37d7da60af329fbc24dad4c798b3a9 Implement importprivkey and test (GideonBature)

Pull request description:

  The JSON-RPC method `importprivkey` does return null. 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](rust-bitcoin/corepc#116)
