Compared to default Admin user who has it "Disabled".
- Create a new admin user with the DW
- Install the Standard Flavor
- Go to Profile - Watchlist: it displays the user page
- Go to Administration - User - Add user
- The Profile - Watchlist will include also XWiki.SearchConfig
This doesn't reproduce for xwiki-platform-distribution-flavor-jetty-hsqldb, where the Administrator's watchlist is empty, still the page is created for the same user add.
