Downgrading to version 38 fails with AttributeError

[Vinod Mangalpally]

Downgrading to version 38 fails with the following error

AttributeError: 'Table' object has no attribute 'filter_by'

See https://github.com/openstack/designate/blob/master/designate/storage/impl_sqlalchemy/migrate_repo/versions/039_support_soa_records.py#L167 for the cause of the error

Also this line https://github.com/openstack/designate/blob/master/designate/storage/impl_sqlalchemy/migrate_repo/versions/039_support_soa_records.py#L170 needs to be corrected to point to recordset_types similar to https://github.com/openstack/designate/blob/master/designate/storage/impl_sqlalchemy/migrate_repo/versions/039_support_soa_records.py#L57
