Test Explorer: "Debug this test" on test explorer executable name doesn't run any tests

[malsyned]

In the Test Explorer, clicking the "Debug this test" button next to the test executable itself causes it to pass -sg <group> with the name of the executable for <group>. Since there is no group with this name, no tests are run and the test executable exits immediately.

My desired behavior here is to just not pass anything and let all the tests run.

Since you know your way around in the code you wanna give it try? Otherwise I can setup my debugger (I must have deleted my mingw installation)

I had the same need, so I created PR #91 to enable debugging the entire test suite.
