Fixes mob and item atcommand sorting issues (#7058)

* Fixes #7055.
* Fixes several atcommands used for mob and item information were not properly accounting for order.
* Resolves an issue where YAML databases were not properly utilizing the cache feature.
* Increased MAX_SEARCH to 10 by default as in renewal there are many more items with duplicated names.
