Fixed bug where failing to read JSON would not create null parse result.
Updated test flow to have Verify() check to see if the given JSON file can be read by the test in question. If if cannot then avoid using that file for any other benchmarking. This avoids the problem where some tests can IE when they don't support the JSON file.
