NullReferenceException when exiting PlayMode in test

Package: Test-Framework


How to reproduce:
1. Open attached Unity project
2. Open Test Runner window
3. Select PlayMode tests
4. Run tests
5. Observe console

Expected result: PlayMode exists successfully.
Actual result: NullReferenceException is thrown.

Reproduced with: 2022.2.0a4, 2022.2.0a1, 2022.1.0b7, 2022.1.0a1, 2021.2.11f1, 2021.2.0a1, 2020.3.29f1, 2020.3.0f1, 2019.4.36f1, 2019.4.0f1.

Full error:
NullReferenceException: Object reference not set to an instance of an object
UnityEngine.TestTools.TestRunner.PlaymodeTestsController+<TestRunnerCoroutine>d__15.MoveNext () (at Library/PackageCache/com.unity.test-framework@1.1.30/UnityEngine.TestRunner/TestRunner/PlaymodeTestsController.cs:74)
UnityEngine.SetupCoroutine.InvokeMoveNext (System.Collections.IEnumerator enumerator, System.IntPtr returnValueAddress) (at <84f51b1b0ff2473ca787c217e1eda8b9>:0)

This mostly causes issues when there is DontDestroyOnLoad object with a static value in a scene. It remains through all the tests and it's not unloaded between tests.
In the attached image you can see that test fails because it's canceled by user.
