DifferenceEngine: show undo links for non-text content

In Ia94521b78 I introduced code that would suppress undo links in diffs
of non-textual content. However, extensions that define non-textual
content, such as Wikibase, may override action handles to provide undo
functionality. So my reasoning for removing these links was flawed.
