Fix issue using query builder first() method (in case with usage outside the Laravel)

[bTokman]

In my case when i using the query builder outside the Laravel app i catching error

Fatal error: Uncaught Error: Call to a member function first() on array in /application/vendor/illuminate/database/Concerns/BuildsQueries.php on line 77

In the new versions of illuminate/database BuildsQueries first() method looks like

public function first($columns = ['*'])
    {
        return $this->take(1)->get($columns)->first();
    }

So it means that get() method must return collection not the array. I made the simple change that would fix this issue.
