Make Device Test results specify platform in names (#121)

One drawback to a shared test project is that the namespace and class names aren’t descriptive of the platform they are running on.  When merging all the test results in CI systems, we lose the ability to easily identify where a test case was ran (especially if it failed).

This will quickly replace some text in the test results file to be specific about the platform each test was run on.
