Fix creative mode inventory search crash
Before this patch it was possible for any user to to crash Minetest in
creative mode. This was possible because queries in the search field
were interpreted as search patterns for string.find().

A search for a single square bracket would reliably crash the server.
Also, a search for 6000 times the string “a?” would hang the server.

The solution to both bugs is to not interpret the query as a pattern.
