Type error when using Codeception 5th version

More information:
If you uses specify out of box (as described in github page), it will throw an TypeError: `Codeception\Specify\SpecifyTest::run(): Return value must be of type PHPUnit\Framework\TestResult, null returned`

I have looked in and noticed that `TestResult` object was got from `TestCase` object. That how it works in 4th version. And codeception runs test using `TestCase::run` method. But in 5th version it uses `TestCaseWrapper`. That's why there is not `TestResult` object in `TestCase` to give it in Specify

Codeception has default configurations (just after codecept bootstrap)

从 SpecifyTest::run() 开始，跟踪 Codeception 5 通过 TestCaseWrapper 的执行路径，并比较 TestResult 在版本 4 中是如何获取的。复现文档中记载的开箱即用的 Specify 设置，并在 TypeError 不再发生时验证执行完成。
