2d469bfd479a6797df624c506aaad069ce2515cf Implement encryptwallet method and test (GideonBature)

Pull request description:

  The JSON-RPC method `encryptwallet` 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](rust-bitcoin/corepc#116)
