fix: posts sorting on sidebar

[dyudyunov]

Description

Fix wrong sorting when a user creates several posts without the page reloading.

Steps to reproduce

1. [Precondition] The new discussions experience (discussions sidebar) should be enabled
2. Navigate to any course unit where the discussions sidebar is enabled
3. Create a new post.
4. Click on the "Back to list" button. Note that the default sorting is used (most recent first) and it's correct.
5. Create another post without reloading the page
6. Click on the "Back to list" button and check the result

Actual result

The second created post is the last in the list (the same for any number of posts created additionally).

Expected result (with the fix applied)

Sorting works as expected - most recent posts are displayed first.

Additional Notes

• Reproduces only with the discussions sidebar inside the Learning MFE.
  That's because when you create a post in the Discussions MFE itself - you will be navigated to the "My Posts" tab and the list of the posts will always be fetched.
• Sorting works as expected after the page is reloaded.

My changes require further improvements - there are unneeded additional GET requests to the threads endpoint.

I will change the status to Draft for now

I figured out how to get rid of the unneeded API call, now it's ready for the review

Tests CI seems to be canceled because of the timeout Error: The operation was canceled. Failing after 360m

Does anyone know the reason?

@dyudyunov Not sure about it.

Rebased on fresh master branch

Hope it will fix the pipeline timeout issue

Hi @dyudyunov! Do you still need help with this? If so, I can look into it for you.

[dyudyunov]

Hi @mphilbrick211

Sorry for the delayed response

Yes, I need some help here, the timeout issue is still reproducing (I rebased the working branch today to re-check) and I don't know the reason. I also saw that other PRs have the same issue
