Visual Studio does not run all tests when the test discovery failed on one test in a class

[DerAlbertCom]

Visual Studio Test Runner does not run all xUnit Tests when the test discovery throws an exception. I filed this also under: microsoft/vstest#2122

Steps to reproduce

Checkout the repository https://github.com/DerAlbertCom/MisbehavingUnittestRunners it in Visual Studio. More details why the problem occurs is also there.

Expected behavior

At least the exception within the test discovery shows up. And not silently not run the test without any reason. Also excepting to show a skip reason in the test runner.

Actual behavior

Test withing Visual Studio 2019 16.2
.
In the sample repository are 6 Unit Test, 2 of are not run without any hint because of an exception within the test discovery on one test.

In microsoft/vstest#2123 is mentioned that the test adapter seems to capture the exception during discovery, because of that the Test2 and Test3 are not run and lost.
