asap uses timer, not MutationObserver, in Safari

1

asap does not use `makeRequestCallFromMutationObserver` because `if (typeof BrowserMutationObserver === "function")` fails: `typeof MutationObserver` returns "object" in Safari (observed in versions 7-9). `Object.prototype.toString.call(MutationObserver)` returns "[object MutationObserverConstructor]".
