20936	When logging out/ending a session, don't create a new, empty session	Matt Robenolt	Matt Robenolt	"Previously, when logging out, the existing session is overwritten by a new sessionid instead of deleting the session all together.

This behavior adds overhead by creating a new session record in whichever backend being used, db, cache, etc.

This extra session is unnecessary at the time since no session data is meant to be preserved when explicitly logging out.
