OutputPageTest should be independent of $wgResourceLoaderDebug setting

`OutputPageTest::testMakeResourceLoaderLink()` and
`OutputPageTest::testBuildExemptModules()` tried to force
`$wgResourceLoaderDebug=false` before running the test, but they
neglected to clear the resource loader debug cache
(`ResourceLoader::clearCache()`) so the user's local setting of
`$wgResourceLoaderDebug` would be used despite it all.
