Part of ENG-10477

To be able to restore in here, we need to get auth metadata. We can't just call getAuthMetadata because we need to wait for re-render to make sure the store is populated.

We can:

1. Update performLogIn to return CSAT and userID
2. Implement some waiting logic to execute restore after store is populated with auth metadata, but this is complicated, and we need to deal with many race conditions.

I implemented option 1.

Depends on D14520
