Alembic migrations: Only exists contract version in database

I had a clean environment(code version: stable/queens), and run DB update operations.

Step 1. First upgrade to Mitaka:
# neutron-db-manage upgrade mitaka

Result: all things runs ok, the neutron and subprojects are upgrade to Mitaka version.

Step 2. Then runs the following command:
# neutron-db-manage upgrade expand

Result: meets an error here, exception:
# neutron-db-manage upgrade --expand

alembic.script.revision.ResolutionError: No such revision or branch 'expand'

After Step 1, I found that only one record(Mitaka contract head) in alembic_version table:
MariaDB [neutron]> select * from alembic_version;
+-------------+
| version_num |
+-------------+
| 4ffceebfcdc |
+-------------+
1 row in set (0.00 sec)

There was missing expand head in alembic_version table.
