Improperly changed user

[JPedroCh]

Describe the bug
When two users change the language and navigate from my stuff tab to collection, the username is changed to another one ( the other user must be also changing the language). When trying to change the language again with the different username, the page breaks with 403 error.

To reproduce the bug
Steps to reproduce the behavior:

1. Log in
2. Go to my stuff page
3. Click on select your language
4. Select another language
5. Go to collection
6. See the username of another user
7. Click on select your language again
8. Select another language
9. See the 403 error

Expected behavior
It is expected to just change the language when selected, without affecting the logged user.

@JPedroCh , this is a very well-documented bug! Thank you!

We can't reproduce the error. Would you be available for a call so we can try to replicate it together?
