More specific typeof check for polyfilled Symbol
More specific typeof check for polyfilled Symbol

Let's get more specific with our tests. Symbol has to be a function if
it's a polyfill. There are no object polyfills out there. (If there is,
ping me and I'll add support)

Instead of checking if Symbol is undefined, let's check if it's a
function instead since instanceof is depending that Symbol is already a
function.
