GT Performance 1.0.5

Fixed

• Uninstalling with data removal enabled deleted this plugin's options and tables but never touched the filesystem, so wp-content/cache/gt-performance/ survived in full: cached HTML, generated CSS and JavaScript, logs, and both configuration files. redis-config.json.php holds a host, username, and password. The guard kept those unreadable over HTTP, but someone who asked for their data to be removed should not be left with credentials in wp-content. Uninstall now removes the directory, resolving the path the way Core\Paths does and confirming with realpath() that it still sits inside wp-content before deleting anything. wp-content/cache itself is left for other plugins.
