Currently, unit testcases emit FutureWarnings from oslo.versionedobjects about invalid uuids as documented here[1]. This commit changes these tests to use valid uuids so that when they are run these warnings are no longer emitted. [1] http://docs.openstack.org/developer/oslo.versionedobjects/api/fields.html#oslo_versionedobjects.fields.UUIDField Closes-Bug: #1557378 Change-Id: I21a60e916e183f7c0fc6193d4b7caa88ae3b6d56
