LiveObject: Inconsistent error handling in async methods

[sacOO7]

• Currently, when asynchronous methods throw an exception, our callback mechanism only captures the ErrorInfo from the exception.
• This ErrorInfo is then passed through the onError callback method.
• In contrast, for blocking methods, the thrown exception is returned to the caller as-is, without being wrapped or altered.

• The solution is to return the exception unchanged, rather than wrapping or modifying it, to maintain better transparency.
• So new Callback will look like

public interface ObjectsCallback<T> {
    /**
     * Called when the associated operation completes successfully,
     */
    void onSuccess(T result);

    /**
     * Called when the associated operation completes with an error.
     * @param reason information about the error.
     */
    void onError(AblyException exception);
}
