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)`)
