RunTests target hides exception thrown during NUnit fixture setup

[sbomer]

I hit a scenario where running tests via arcade hides some important messages indicating that test setup failed and some tests were skipped. Running tests normally using the dotnet sdk surfaces this information as expected. Repro steps:

• git clone https://github.com/dotnet/cecil
• cd cecil
• git checkout ff87dfd51654949f6379059c258b7f8c13e10d29
• ./build.sh -test (succeeds without indicating there were any issues)
