Deleting an account and logging in to an existing account takes you to account deleted page

Steps to reproduce

1. Through whatever means is easiest, create and activate an account you’re willing to delete

2. Log in to that account

3. Delete it:

   1. Hi, username! > My Dashboard > Profile > Delete My Account

   2. Confirm that you wish to go ahead with the deletion

4. Close the tab

5. Open https://test.archiveofourown.org in a new tab

6. Log in to a different account

What happens

You are redirected to https://test.archiveofourown.org/delete_confirmation, which says “Account deleted!” and a bunch of other words, but you’re not gonna read any of those because you’ll be too busy going, “WHAT.”

What should happen

You should be redirected to either your dashboard or the homepage.
