restiming entries not added to beacon on xhr_load

[vkbandi]

Hi,

When xhr_load event is invoked, the following line passes data.restiming as parameter r to the addToBeacon function

boomerang/plugins/restiming.js

Lines 1759 to 1773 in c0cbec6

	xhr_load: function(data) {
	if (data && data.restiming) {
	// put RT data on beacon
	addToBeacon(data.restiming);
	}
	if (this.complete) {
	return;
	}
	// page load might not have happened, or will happen later, so
	// set us as complete so we don't hold the page load
	this.complete = true;
	BOOMR.sendBeacon();
	},

The addToBeacon function again checks for r.restiming, in the xhr_load event call this will be undefined as r is the restiming data and it will not have a field called restiming inside it

boomerang/plugins/restiming.js

Lines 1693 to 1699 in c0cbec6

	function addToBeacon(r) {
	BOOMR.addVar("restiming", JSON.stringify(r.restiming), true);
	if (r.servertiming.length) {
	BOOMR.addVar("servertiming", BOOMR.utils.serializeForUrl(r.servertiming), true);
	}
	}

This causes the restiming entries added to the beacon on xhr_load to be missed in the beacon
