DOH log needs to escape XML

[Adam Peller]

see #7189. The output stripped out tags in the content of the query test upon failure.

    var doc = dojox.data.dom.createDocument(["","One","Two","Three","Four",""].join(""));

should look like

								var doc = dojox.data.dom.createDocument([
									"<ResultSet>",
										"<Result>One</Result>",
										"<RESULT>Two</RESULT>",
										"<result>Three</result>",
										"<result>Four</result>",
									"</ResultSet>"
								].join("")
								);

tests/_base/query.html has strings like

"<result>foo</result>"

on the console, all we see when it prints out the function source is "foo"

(In [14439]) Fixes #7193 was not escaping a string in a certain condition when it was within an object !strict

[Adam Peller]

the query test code still isn't escaped, unfortunately.

(In [14461]) Use XML entities in log. Fixes #7193 !strict
