Don't parse results.test when attribute not present

This is a fix for the error that appears during a chrome renderer crash...

We detected that the Chromium Renderer process just crashed.

This is the equivalent to seeing the 'sad face' when Chrome dies.

This can happen for a number of different reasons:

- You wrote an endless loop and you must fix your own code
- You are running Docker (there is an easy fix for this: see link below)
- You are running lots of tests on a memory intense application.
    - Try enabling experimentalMemoryManagement in your config file.
    - Try lowering numTestsKeptInMemory in your config file.
- You are running in a memory starved VM environment.
    - Try enabling experimentalMemoryManagement in your config file.
    - Try lowering numTestsKeptInMemory in your config file.
- There are problems with your GPU / GPU drivers
- There are browser bugs in Chromium
