 In WP_Site_Query, queries are cached as a list of site ids. The key cache
 is generated using the query args. But even through the values in the
 cache are the same, if you query by `'fields' => 'all'` and `'fields' =>
 'ids'`, two caches are generated. By unsetting the `'fields'` arg before
 generating the cache key, both queries will use the same cache.
