Title: prevent infinite redirect on log in when already logged in

The app was infinitely redirecting when logging in twice.

To reproduce:
- start scala sample
- goto .../login page & log in with google OAuth
- login goes fine
- goto .../login page again & try to log in again

Result:
- app keeps redirecting until browser detects loop

This commit fixes the behaviour (but it might have broken something else if it goes to ```session.get(SecureSocial.ProviderKey)``` for a specific reason).
Please review.
