Sergey Biryukov ad93e6387c Cache API: Validate cache key in WP_Object_Cache methods. ... Some plugins may call the `wp_cache_*()` functions with an empty string, `false`, or `null` as cache key, usually as a result of not checking the return value of another function that's used as the key. Previously, this was silently failing, leading to odd behavior at best and often breakage due to key collisions. A valid cache key must be either an integer number or a non-empty string. This commit introduces a quick type check on the given cache keys and adds a `_doing_it_wrong()` message that should help plugin developers to notice these issues quicker. Includes: * A check in `update_user_caches()` and `clean_user_cache()` to make sure user email is not empty before being cached or removed from cache, as it is technically possible to create a user with empty email via `wp_insert_user()`. * Some minor cleanup in unit tests where the email was passed to `wp_insert_user()` incorrectly or was unintentionally reset.
