Do an HTMLCacheUpdate of templatelinks on page creation

When a page is created, anything that's trying to transclude that page
needs to have an HTMLCacheUpdate run on it. But that's not currently
happening.

Normal template transclusion happens to get updates only because
transclusion of a nonexistent template is rendered as a link to that
template, which registers a pagelink, and pagelinks *are* being updated
on page creation to cause redlinks to turn blue.
