Controller Reinitialization Issue: onInit and onReady Not Triggered When Returning to a Page After Disposal

[shenzhenMirren]

### Describe the bug
When navigating from Page A to Page B, Page B's view contains an asynchronous callback that calls methods on the controller. 

Upon leaving Page B and returning to Page A, the controller's `onDelete` method is triggered, and the controller is disposed as expected. 

However, due to the asynchronous callback in Page B still referencing the controller, it gets re-initialized. 

When navigating back to Page B again, the controller already exists, and `onInit` or `onReady` are not called, leading to unexpected behavior and missing initialization.

### Reproduction code  
```dart
import 'package:flutter/material.dart';
import 'package:flutter_async_view_test/home/home_controller.dart';
import 'package:get/get.dart';

class HomeView extends GetView<HomeController> {
  const HomeView({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          child: const Text('Next Route'),
          onPressed: () {
            Get.toNamed('/second', arguments: {"data": "hello"});
          },
        ),
      ),
    );
  }
}

import 'package:flutter/material.dart';
import 'package:flutter_async_view_test/second/second_controller.dart';
import 'package:get/get.dart';

class SecondView extends GetView<SecondController> {
  const SecondView({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text("Second"),
      ),
      body: Center(
        child: Column(
          children: [
            Obx(() => Text("Get.arguments is: ${controller.data.value}")),
            ElevatedButton(
              onPressed: () async {
                Future.delayed(
                  const Duration(seconds: 3),
                  () {
                    debugPrint("There's a problem here...");
                    controller.doSomething();
                  },
                );
              },
              child: const Text("Click me and go back"),
            )
          ],
        ),
      ),
    );
  }
}

import 'package:flutter/material.dart';
import 'package:get/get.dart';

class SecondController extends GetxController {
  final data = "".obs;
  @override
  void onInit() {
    super.onInit();
    debugPrint("SecondController on init->${Get.arguments}");
    if (Get.arguments != null) {
      data.value = Get.arguments['data'] ?? '';
    }
  }

  void doSomething() {
    debugPrint("call do something");
  }
}

To Reproduce
Steps to reproduce the behavior:

1. Run the app and start on Page A.
2. Navigate to Page B.
3. Leave Page B and return to Page A.
4. Observe that the controller's onClose is triggered.
5. Wait for the asynchronous task to complete, which re-initializes the controller.
6. Navigate back to Page B.
7. Observe that the controller's onInit and onReady methods are not called.

Expected behavior
When returning to Page B after the controller has been disposed, the controller should be fully re-initialized, including triggering onInit and onReady.
