Subject: [PATCH 09/21] update db schema(s) for blinding v2 (25-blinding)

This is only the schema change itself; migration to come.

The `users` table will now have only one row per SessionID, and the
`session_id` column will be the 25-blinded id.  Messages which were
signed using either the non-blinded Session ID or the 15-blinded ID will
have that ID set in `alt_column`
