django-celery-results does not respect result_extended flag

[AmitPhulera]

Hi!

As mentioned in celery docs, by default result_extended is set to False in the celery config.

But django-celery-results store args, kwargs and other meta info despite result_extended is set to False.

Here are the reproduction steps

# tasks.py
from celery import shared_task

@shared_task
def some_task(param):
    print(f"{param} was passed")
    return param

Calling the task from django-manage shell

In [1]: from myapp.apps.niceapp.tasks import some_task

# calls the task
In [2]: some_task.delay(["input_2"])
Out[2]: <AsyncResult: ab75a9fb-061c-48a2-a4cb-e85df047e23f>

# Verifying that `result_extended` is set to `False`
In [3]: _2.app.conf.get("result_extended")
Out[3]: False

# helper to view all fields in model object
In [4]: def display_all_fields(s_obj):
   ...:     for f in s_obj._meta.fields:
   ...:         print(f.name, getattr(s_obj, f.name))

# Trying to figure out what all info is stored in db
In [5]: from django_celery_results.models import TaskResult

In [6]: TaskResult.objects.get(task_id=_2.task_id)
Out[6]: <TaskResult: <Task: ab75a9fb-061c-48a2-a4cb-e85df047e23f (SUCCESS)>>

In [7]: display_all_fields(_6)
id 19096
task_id ab75a9fb-061c-48a2-a4cb-e85df047e23f
periodic_task_name None
task_name myapp.apps.niceapp.tasks.some_task
task_args "(['input_2'],)"
task_kwargs "{}"
status SUCCESS
worker celery@work
content_type application/json
content_encoding utf-8
result ["input_2"]
date_created 2022-05-24 07:54:47.677220
date_done 2022-05-24 07:54:47.725070
traceback None
meta {"children": []}

All the metadata is logged which should be stripped.

Is there a reason to ignore this config option? If not, I would be happy to send in a PR to fix this issue.

Thanks.

Stripping out the task_name property like is going to cause a lot of headaches for users of this project... myself included.
