Fix asyncio locks test case

[cykerway]

There are some clear minor mistakes in asyncio locks test case: Duplicate statements and wrong assert function.

The duplicate statements (L846 and L850) might be intentional but the assert function (L856) is obviously wrong.

cpython/Lib/test/test_asyncio/test_locks.py

Lines 845 to 856 in 5185956

	await asyncio.sleep(0)
	self.assertEqual(0, sem._value)
	self.assertEqual(3, len(result))
	self.assertTrue(sem.locked())
	self.assertEqual(1, len(sem._waiters))
	self.assertEqual(0, sem._value)
	self.assertTrue(t1.done())
	self.assertTrue(t1.result())
	race_tasks = [t2, t3, t4]
	done_tasks = [t for t in race_tasks if t.done() and t.result()]
	self.assertTrue(2, len(done_tasks))
