Recently set up a new discourse (Discourse v3.4.0.beta3-dev) on a fresh vps.

When I enable Google Oauth and head to the /signup page and sign up with a new Google user everything goes through Google just fine, however when the Oauth returns to my site I get a JS error in the console of:

```plaintext
rsvp.js:23 Uncaught TypeError: Cannot read properties of undefined (reading 'set')
    at auth-complete.js:145:38
    at Array.forEach (<anonymous>)
    at auth-complete.js:144:57
    at _ (rsvp.js:434:1)

    at B.end (backburner.js.js:589:1)
    at B._runExpiredTimers (backburner.js.js:905:1)

```

However, if I go to the /login page and do the same it works just fine.

The bug also happened when I tried to sign up here so it’s not just an issue with my install.
