batch call parsing does not conform to JSON-RPC 2.0 standard

[janmazak]

AuthProxy.batch_() should use ids to match responses with requests.

According to https://www.jsonrpc.org/specification: "The Response objects being returned from a batch call MAY be returned in any order within the Array. The Client SHOULD match contexts between the set of Request objects and the resulting set of Response objects based on the id member within each Object."

Now it is assumed that the server will keep the order the same.
