Existing User Marked as 'Not Found' in Notification Panel

[shricodev]

Describe the bug

Sometimes, when I receive a reaction notification on my blog post and try to click on the user profile, it redirects me to a profile that does not exist.

NOTE: when I hover over the user profile, it shows this as their profile URL: https://dev.to/diego_reinoso_ec97def42bf and when I visit the URL for that particular user, it shows the 404 page,

However, when I go to my blog stats page and click on the user, it redirects me to this URL: https://dev.to/diego_reinoso

Now, when I click on the user, it redirects me to the correct link for the user, and it exists.

To Reproduce

I am not sure if this is the right way to reproduce the error, as I don't know this for sure (just a guess), but I believe this is happening because when the user signed up and reacted to a post, they had the auto-generated username from DEV, and just after reacting to the post, they changed the username. I believe that is causing the notification URL to be out of sync with the changed username URL.

1. Create a new account with an auto-generated username.
2. React to a post.
3. Change your username to something else.
4. Now, the author of the post will receive a notification with the previous username's URL, which will result in a 404.

Expected behavior

No matter if the user changes their username after reacting to the post, the notification the author receives should include the updated URL for the user.
