sqlite3 backend: not adapted for January 2020 changes

[0-wiz-0]

When updating https://github.com/mozilla-services/syncserver to the latest version using a sqlite3 backend, the tokenserver stopped working.

The logs say:

OperationalError: (sqlite3.OperationalError) no such column: keys_changed_at

 [SQL: select
     uid, generation, client_state, created_at, replaced_at,
     keys_changed_at, node
 from
     users
 where
     email = ?
 and
     service = ?
 order by
     created_at desc, uid desc
 limit
     20

This stopped working (for the sqlite3 backend) with:

    bug: Bring staticnode up-to-date with tokenserver storage

which extended the user table by two columns:

diff --git a/syncserver/staticnode.py b/syncserver/staticnode.py
index 9c73f65..3f58bdf 100644
--- a/syncserver/staticnode.py
+++ b/syncserver/staticnode.py
@@ -41,13 +41,16 @@ users = Table(
     Column("client_state", String(32), nullable=False),
     Column("created_at", BigInteger(), nullable=False),
     Column("replaced_at", BigInteger(), nullable=True),
+    Column("keys_changed_at", BigInteger(), nullable=True),
+    Column("node", String(255), nullable=True),
     Index('lookup_idx', 'email', 'service', 'created_at'),
 )

but my existing sqlite3 database was not updated automatically, and I don't even see a script for updating it.
