Query Folders are incorrectly called "queries" in pop-up notifications

[philrz]

Repro is with Zui commit f6f28ac.

As shown in the attache video, if I right-click on a Query Folder and select Delete, the pop-up notification asks "Are you sure you want to delete this query?". I can tell that the Delete option is intended to allow for deletion of a mix of queries and folders at any level in the hierarchy, and this is indeed handy. However, it would seem ideal if we presented an accurate summary in the notification (e.g. "Are you sure you want to delete 1 folder and 3 queries?"), especially since deleting a folder containing a lot of queries potentially has a much bigger impact than deleting just a single query.
