Boost user name in search all results

When you search for a user in the "All" tab then a user name bears no more importance than other content (that might be published by this user). This causes the user searched for to end up on the last page of "Search All". This was experienced by one of our enterprise clients.

To solve this we can boost the username from 1 to 2. This ensures that if a user is matched in a "Search All" search it is displayed first. (User)names are usually quite unique and when searched for they are usually the goal (if searching for an article, other terms would be used). Therefor having any users come up first in a query has probably no or little downside and a lot of upside.
