    Fix branch order when upgrading to alembic milestone
    
    When using neutron-db-manage to upgrade to a milestone tag,
    the script was not ensuring that the expand branch was
    upgraded before the contract branch. This broke projects
    where contract migrations depend on expand migrations.
