Add EnvTestWithParam::OptionsTest to the ASSERT_STATUS_CHECKED passes (#7283)

Summary:
This test uses database functionality and required more extensive work to get it to pass than the other tests.  The DB functionality required for this test now passes the check.

When it was unclear what the proper behavior was for unchecked status codes, a TODO was added.
