Fix invalid uuids in sheepdog unit tests
Fix invalid uuids in sheepdog unit tests

The sheepdog unit tests emit several FutureWarnings [1]
from oslo_versioned_objects due to use of invalid uuids in
faked test values.

This commit uses values from
cinder/tests/unit/fake_constants.py to resolve this issue.
