Prevent a translation from injecting HTML in change entry labels.
Review Request #9459 — Created Dec. 19, 2017 and submitted
The "Fix it!" text for the change entry label was being injected
directly into a jQuery object, which could allow a translation to
accidentally cause unescaped HTML characters to mess up the page. This
is a simple fix that ensures we're creating a text node.
Tested that the text still showed up.
