Could you explain this a bit. I thought you would have NOTRUN results for tests
that were not run. Instead it looks like we have no results at all?

At this point, results contains only what we were able to determine from the
output or the XML -- it doesn't have anything based on the test. The NOTRUN
results for all tests are over in LocalDeviceTestRun.RunTests on the main
thread.

We could (and at one point, I did) have this create NOTRUN results for
everything in |test|, then update that set w/ |results|, then return everything
that was still NOTRUN as not_run_tests, but that's just a more convoluted
version of this.
