[FrankZwiers]

Description

The search score is not correctly set on elements in the populate function in ElementQuery.php.

Steps to reproduce

1. Make basic template which utilizes search

   {% for entry in craft.entries.search("life").orderBy('score').all() %}
       Title: {{ entry.title }}<br>
       Searchscore: {{ entry.searchScore }}<br><br>
   {% endfor %}

2. Notice searchscore is always empty
