async / await not working due to jasminewd2

I`m trying to use protractor with plain nodejs (not Typescript) and async functions as test callbacks. Unfortunately an error appears telling me that these async functions are no functions.

Stacktrace:

1) some test encountered a declaration exception
  Message:
    Error: async function() {
        await browser.get('https://www.google.com');
    });
} is not a function
  Stack:
    Error: async function () {
            await browser.get('https://www.sixt-neuwagen.de');
    
            let blub = await ekomi.isDisplayed();
            expect(blub).toBe(true);
        } is not a function

        at Object.Module._extensions..js (module.js:580:10)
        at Module.load (module.js:488:32)

Testsuite:

describe('some test', function() {
    it('should do something', async function() {
        await browser.get('https://www.google.com');
    });
});

Reason: (Taken from jasminewd2 index.js)

function validateFunction(functionToValidate) {
  if (functionToValidate && Object.prototype.toString.call(functionToValidate) === '[object Function]') {
    return functionToValidate;
  } else {
    throw Error(functionToValidate + ' is not a function');
  }
}

Async functions checked with Object.prototype.toString.call(functionToValidate) evaluate to [object AsyncFunction].

Env:

• Node Version: 7.7.1
• Protractor Version: 5.1.1
• jasminewd2 Version: 2.0.0

@heathkit, I was able to use async/await (without Babel) in my protractor tests after applying angular/jasminewd#87

Thanks for the fix! I’ll take a look.
