Store hash of session key

Browse source 
Summary:
This prevents security by obscurity.
If I have read-only access to the database then I can pretend to be any logged-in user.

I've used `PhabricatorHash::digest()` (even though we don't need salt as the hashed string is random) to be compatible with user log.

Test Plan:
Applied patch.
Verified I'm still logged in.
Logged out.
Logged in.
