However, there is a race here and it is possible that the `JVMTI_PHASE_LIVE` phase is reached before any system thread has been started. There is no way to fix the test so, it is being removed.

Marked as reviewed by amenkov (Reviewer).

I thought if we need some sanity test for ThreadStart event with can_generate_early_vmstart capability, but looking at the spec I see no relations between them. So it's unclear what was the purpose of the test.
