Fix SQLite session_id
(#2977)
This fixes an issue with device_id/session_ids. If a `device_id` is reused, we would reuse the same `session_id`, since we delete one device and insert a new one directly, resulting in the query to get a new `session_id` to return the previous session_id. (`SELECT count(access_token)`)
