Fixed more tests

refs 8630be5a87

- referenced commit skipped current user and proxy service population when `skipAuthSuccessHandler` was set but the population is needed during setup
- `skipAuthSuccessHandler` is used for skipping the post-authentication transition rather than skipping all post-auth behaviour so the the post-auth behaviour was reintroduced but put in a guard so we don't try to do it again when it's already been run
