Original change's description:
> Enable call stacks in crash reports tests
>
>
> This is a follow up change to enable the tests for the call stacks in
> crash reports feature and address the flakiness.
>
> The problem is that when we simulate an unresponsive renderer to
> start the workflow to collect the js call stack. The next call which
> is to shut down the renderer process may execute and complete before
> we can retrieve the call stack.
