Change No Results Found Message for Users

Purpose: Correcting the no results found error that was previously specified. It was originally requested that we reference the search term in the no results found message, but that's a bad idea because you can get no results without having entered any search terms (using filters alone).

1. Scenario
   • Given the User List in the Users app
   • When applied search and filters return no results
   • Then the following message should be displayed:
     • No results found. Please check your spelling and filters.
