Promise.all arguments is null or undefined

[OhadTs1985]

Hi,

I've noticed that when running the following code on browsers that supports promises and browsers that doesn't support (with this the polyfill) i get a different result:

Promise.all(null) .then(function () { console.log('then'); }) .catch(function (e) { console.log('catch', e); });

Supported browsers result:
Calling the 'catch' statement with an error of 'TypeError'.

Unsupported browsers (with the polyfill):
Throws an error on the arguments slice, doesn't call the 'catch' statement.

Is this the behavior aimed for in this polyfill?

Thanks,

It should behave the same. Would you mind creating a pull request?
