NodeList.adopt does not work when it is passed a NodeList as an argument

[ptwobrussell]

/* Works */
n = document.createElement("DIV");
n.innerHTML="foobar";
dojo.query("#_div1").adopt(n);


/* Doesn't Work */
n = document.createElement("DIV");
n.innerHTML="foobar";
nl = new dojo.NodeList(n);
dojo.query("#_div1").adopt([n]);

The reason that the latter doesn't work is because the dojo.query call inside of NodeList?.adopt is creating a nested NodeList?, which is getting iterated over in the forEach call. Simple fix is to either index [0] into the dojo.query call or otherwise "fix" dojo.query to act like a no-op when it is passed a NodeList?.

(In [11045]) ensure that dojo.query passes back a node list if it's inadvertently passed in. Fixes #4825
