Ignore files when debugging tests.

[zeel01]

Normally when running the debugger the launch.json file can be used to control various settings including skipFiles which allows us to, among other things, ignore files in node_modules. However it doesn't appear that the test running uses any of the profiles from the launch.json (if I delete the file, the test runner happily starts a debugging sessions anyway). As such, there doesn't appear to be a way to configure it so the debugger will skip certain files?

It would nice if this were an option (or if it's already possible, it would be great if there was a note in the readme). Generally it would be cool if we configure all the usual debugging options, but ignoring code we didn't write is the most important one imo.
