Implements proper UUID format for test_compute_mgr.
Implements proper UUID format for test_compute_mgr.

Currently some of the unittests are using non valid UUID format
for the FieldType UUID.

This is preparation work to add UUID validation in the
oslo_versionedobjects/fields.py.

Without this change adding validation will cause tests to fail.
