Case list select no search results message

FB123578: Add a configurable "No Results" message to inline search

If there's an action enabled, it's possible to see "No search results" and then see the action below the message. This is a little odd, but the action isn't a search result, so it's consistent.
Can we update this to have an argument like 

"No results for your search: "${0}"" 

So it's a bit more clear to people who inadvertently enter a query (which does happen) that there is something that's driving the search?
