Uninstalling Quick Cache after migrating to ZenCache results in missing define('WP_CACHE', TRUE) #450

In v150314 we fixed a zero-byte advanced-cache.php bug related to uninstalling Quick Cache after migrating over to ZenCache (see #432). However, it seems that uninstalling Quick Cache is also removing the define('WP_CACHE', TRUE); from the wp-config.php file.

So, even though ZenCache is now ensuring that advanced-cache.php is populated and correct, the cache is not being used because define('WP_CACHE', TRUE); is missing from wp-config.php.

It looks like we just need to add a call to add_wp_cache_to_wp_config() inside check_advanced_cache() right here, so that whenever the advanced-cache.php file is missing or empty we also check to make sure define('WP_CACHE', TRUE); is set in the wp-config.php file.

@jaswsinc Does that sound right to you?
