Switching accounts results in a 403: Delegation denied error

**Describe the bug**
I'm running into an odd bug where I can can successfully switch between multiple Google accounts (say from account 1 to account 2), but Gmail (or any other Google service) believes I'm still logged in account 1.

**To Reproduce**
Steps to reproduce the behavior:
1. Login with Google account 1
2. Observe that the API calls to Gmail are successful
3. Logout and login with Google account 2
4. Observe that the app received a new auth token and account 2's email address
5. Any call to Gmail will now result in a "403: Delegation denied error for "
6. Kill and restart the app
7. The app will restore the previous session without user interaction using `GIDSignIn.sharedInstance.restorePreviousSignIn`
8. Observe Google account 2's session was restored and now all calls to Gmail are successful

1. Login with Google account 1
2. Observe that the API calls to Gmail are successful
3. Logout and login with Google account 2
4. Observe that the app received a new auth token and account 2's email address
5. Any call to Gmail will now result in a "403: Delegation denied error for "
6. Logout and login with Google account 1
7. Observe that the app received a new auth token and account 1's email address
8. Calls to Gmail for account 1 are successful

**Expected behavior**
I expect to be able to log out and log in with a different account successfully

**Screenshots**
None.

**Environment**
- Device: Simulator and iPhone 12
- OS: iOS 16.2
- Browser: Swift app

**Additional context**
Add any other context about the problem here.

Inizia con il flusso di cambio account e GIDSignIn.sharedInstance.restorePreviousSignIn, confrontando lo stato del token e della sessione prima e dopo il logout e il login. Riproduci la sequenza di richieste Gmail su iOS 16.2; il lavoro è completato quando il passaggio dall’account 1 all’account 2 fa sì che le chiamate successive a Google API utilizzino l’account 2 senza richiedere il riavvio dell’app.
