[site-reviews] fix install error (directory exists)

/**
 * WordPress automatic updates can sometimes fail when updating a plugin. Common reasons are server timeouts,
 * permission issues, or a plugin script is still in use when WordPress attempts to delete the plugin. When
 * this happens, you may be left with an empty plugin folder which makes it impossible to reinstall the
 * plugin (since the plugin folder still exists).
 *
 * If this has happened to you with Site Reviews, then this snippet will tell WordPress to delete the
 * "site-reviews" folder from your plugins directory when installing the plugin.
 *
 * !! IMPORTANT !! Please remove or disable this snippet once you have finished reinstalling Site Reviews.
 *
 * @param array $options
