Strongly speaking, the update of SelfSuspendDisabledTest is not needed. But I feel it is worth to keep it.

This goes to my surprise that we didn't have a test already but you've found it, and found that it should have caught this bug except that it has been changed. Good to find this and I that is the right place to have a unit test for GetThreadState.
