Simple fix for OutputPage::makeResourceLoaderLink
If a ResourceLoaderWikiModule (user or site) is empty, i.e. the relevant pages doesn't exist, there should be no link to it from the html to avoid unnecessary requests.
Currently, it doesn't only output the link, but also adds a version parameter with the current timestamp, which bypasses all caches. This is due to a bug in OutputPage::makeResourceLoaderLink, where the modifiedTimestamp of the module is rounded to 0 if it returns 1.
This bug occurs in the following circumstances:
- For the site module, if MediaWiki:Common.js and MediaWiki:<Skin>.js is empty.
- For the user css module, if not logged in.
- For the user js module, if logged in and the user js pages are empty.
Simple fix attached.
