Qunit test

mediawiki.Title.js converts the extension (or what it thinks is the extension) to lowercase. This is only a good thing when you want to normalize user input for a new file, if you want to get information about an already existing file or the page is in some other namespace, converting things behind a dot to lowercase is the wrong behavior.

The patch adds a qunit test that fails at the moment, since "User:ABC.DEF" is converted to "User:ABC.def".
