Browser query-test runner doesnt report test timeouts and crashed tests correctly

[arindam1993]

Discovered by @ryanhamley, this is two issues that are related. If a test crashes, the exception gets silently caught by the test runner and the callstack exits causing t.end() to never be called, resulting in the test timing out.

The code that generates the visualization then crashes as its unable to parse the timeout metaData correctly.
