1.2.2.b2 breaks ajaxQueue plugin's queue mode, defect in queue()

[joern]

Running plugins/ajaxQueue/test/ with 1.2.2b2 doesn't start any requests for test 3 and 4, worked with 1.2.1.

Tracked down to a check in queue()'s each, line 2985:

if ( this.nodeType != 1)
	return;

Dunno what that guard is doing, but removing it fixes ajaxQueue.

Fixed in [4283] by removing the check.
