OutputPage: Reduce getTitleInfo() calls (improve preloading)
* Remove filter between $moduleStyles and preloadTitleInfo().
Previously, this was filtering out wiki modules created by
gadgets and extensions. Still causing a couple of direct queries
from getTitleInfo().
* Store __METHOD__ in $fname outside getWithSetCallback.
This way queries are logged as either getTitleInfo or preloadTitleInfo.
This regressed in
0852a000a5, after which the latter was logged
as "::{closure}".
