testfx: MSTest 3.0.1 is broken when using deployment items

Describe the bug

Found while verifying https://github.com/microsoft/testfx/issues/1437.

Steps To Reproduce

1. Create UnitTest project in Visual Studio 2022.
2. Make sure target framework is .NET Framework 4.8.
3. Add .runsettings file.
4. Add a deployment item.
5. Build and execute unit tests using vstest.console.exe: "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\Extensions\TestPlatform\vstest.console.exe" TestProject1\bin\Debug\net48\TestProject1.dll /Settings:"TestProject1\local.runsettings" /TestAdapterPath:TestProject1\bin\Debug\net48

Expected behavior

Tests execute.

Actual behavior

Tests do not execute.

Additional context

See attached sample project TestProject1.zip.
