`GIDSignIn.sharedInstance.signIn(...)` is requesting more scopes than it should on version 7.1.0

**Describe the bug**
I was updating Google Sign-In in our app from version 6.0.2 to version 7.1.0 and I noticed that even though we're not requesting any additional scopes, `GIDSignIn.sharedInstance.signIn(...)` is presenting a page after login asking the user to give additional permissions before completing the Sign-In flow.

This wasn't happening previously when we were using version 6.0.2.

**To Reproduce**
Steps to reproduce the behavior:

1. Use this call to initiate the Sign-In flow:

```swift
GIDSignIn.sharedInstance.signOut()
GIDSignIn.sharedInstance.configuration = GIDConfiguration(clientID: "...our client ID")

GIDSignIn.sharedInstance.signIn(
withPresenting: presentingViewController,
completion: { [weak self] result, error in
// ... complete login
}
}
```

2. Run the app on the simulator or a device.
3. Initiate the Sign-in flow.

**Expected behavior**
No additional scopes should be requested after completing Sign-In with Google.
