Fix start info clock tests

Both of these tests are flaky due to how quickly the test can run,
resulting in the clock not actually advancing as expected.

For the ordering test, add a 1ms delay between timestamps thereby
guaranteeing that the time advances.

For the persistence test, change the check to include equals as a valid
pass case. This is ok because it still ensures that the clock was loaded
from disk rather than being initialized as new.

Test: run each test 15 times, all pass
