We can easily avoid a read on the website table when serving the
homepage by simply caching the website.homepage_id value and then
browsing the record (no query needed) instead of reading it on the
website record.
While this code is not really elegant, it seems like a good tradeoff to
gain a query on this particular homepage serve controller, which is the
main entry point of a website and generally the page the more often
served.
