Currently, unit testcases of api 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.
Made changes to project_id in fakes.py to use valid project_id
which removes warnings related to invalid uuids in testcases.
Also made changes to project_id in JSON headers to use valid
uuids in functional testcases same as that in unit testcases.
