    Add volumes table definition when migrating to 67

    When migrating DB to 67 readd_iscsi_targets_table,
    we will add foreign key "volumes.id", but we miss
    to define the volumes table, that will cause the
    migrating process fail: 'NoReferencedTableError'.

    Fix this issue by adding volume table definition
    before creating iscsi_targets table. test is
    added as well.
