Subject: [PATCH] resourceloader: Optimize WikiModule preload for reqs without
 wiki modules

Currently it was still going through fetchTitleInfo() with an empty array on
the majority of requests without wiki modules, e.g. load.php?modules=jquery.

Bug: T158813
Change-Id: Ie33a2b4da572bb30b2e7a69db07790724ec2f03f
