* Fix test for TemplateStylesFontFaceAtRuleSanitizer so it's actually run
* Hack up a broken Sanitizer to test a code path in
TemplateStylesContent::sanitize() that handles such things.
* Ignore an InvalidArgumentException in TemplateStylesContent::processError()
that's not worth checking. User input can't hit that, only logic bugs.
* Ignore TemplateStylesHooks::getConfig(), it's tested but gets called
before PHPUnit starts counting.
* Test TemplateStylesHooksTest::onCodeEditorGetPageLanguage()
* Test $wgTemplateStylesDisable
* Test a back-compat code path in TemplateStylesHooks::handleTag().
