title: LARAVEL UNIT TEST - Opposite of seeInDatabase
body: <p>In Laravel 5.1 there is a method that asset if some data are in database using the seeInDatabase($table,$fields)...</p>
  
  <p>Is there a way to assert if the some data arent in database? Something like dontSeeInDatabase... Similiar to <a href="http://laravel.com/api/5.1/Illuminate/Foundation/Testing/CrawlerTrait.html#method_dontSeeJson" rel="noreferrer">dontSeeJson</a> </p>
