Add Printk Traces to ThreadPool Unit Tests

Some ThreadPool unit tests that test crashed tasks were
missing printk logs to indicate the crashes were expected.
This creates confusion when debugging printk logs. This commit
adds the traces to indicate the crashes are expected and are part
of the test.
