  1. fix regex in utils.stackTraceFilter to prevent ReDoS mochajs#3416 

    if the stack trace begins with a large error message (>= 20k charactors), and user leaves `--full-trace` disabled, `utils.stackTraceFilter()` takes ages to finish. Large error messages is quite possible when user makes containment assertions such as `expect(content).to.contain(word)`.
