Preconditions
Sign in to SUMO

Steps to reproduce
Steps to reproduce the behavior:

1. Go to https://support.allizom.org/en-US/users/edit
2. Click on the "Close account and delete all profile information" option and proceed with the account deletion.

Expected behavior
After the username was given to confirm and the deletion was performed by clicking the "Delete Your Account" from the prompt, the user is automatically signed out and redirected to the "Your account was successfully closed!" page (https://support.allizom.org/en-US/users/close_account) - Similar to prod and dev

Actual behavior
The confirmation prompt is stuck and the user is signed out only after a page refresh.

Additional context
This issue is reproducible in stage and I suspect is a regression caused by the change in mozilla/kitsune#6301
