tests: Update VU database for obj tracker tests
tests: Update VU database for obj tracker tests

Change the testname column from Unknown to None for all
error enums referenced in object tracker.  This is a good
starting point because there are vitually no tests explicitly
written to test object tracker checks.
A later commit will update the few rows in the database
with the names of the tests that currently exist.
