Ordering unaggregated results is not done anymore

I'm not sure, but I think this code was related with doing exactly that:

- // Order by most recent or id.
+    // Order by most recent through time interval field.
     if ($this->getTimeIntervalField()) {
       $query->sort($this->getTimeIntervalField(), 'DESC');
     }
-    else {
-      $query->sort($entity_info->getKey('id'), 'DESC');
-    }
+    // Always order by primary key to solve the second granularity issue.
+    $query->sort($entity_info->getKey('id'), 'DESC');

Here is the patch, it basically just adds the if statement from the first comment to order the results by timestamp configured in the settings. Ordering by id isn't possible with databases, there are various IDs and no way to get a primary key as a fallback.

Tests are fixed! There are more results for the successful login sensor now that the other tests have been uncommented.

Rebased, if it really was necessary.

Edit: Looks the same, was unnecessary :D.
