Should show stacktrace when exception is thrown

[sswaroopgupta]

Expected behavior
Should show stacktrace when exception is thrown

Actual behavior

• does not show the stack trace for throw 'Error'

throw 'Error2'; // generates an exception with a string value
throw 42;       // generates an exception with the value 42
throw true;     // generates an exception with the value true

• Works for an assertion failure
• Works for throw new Error('Unimplemented Step');

@sguptatw That's not an issue with the plugin. It's the way how nodejs handle errors.
throw "Error" is not same as throw new Error("Error"). first one is a primitive, not an object. throwing a primitive will not capture any stack trace.
