Update git submodules

* Update extensions/MediaSearch from branch 'wmf/1.38.0-wmf.13'
  to af3dcaf7cdd1a71a8cedfbf1f4558f168cbaafde
  - Don't boot users with title="Special:MediaSearch" back to old search page
    
    The PHP UI supports the same search filters that the JS UI does
    (file type, file size, etc). If a no-JS user lands on the MediaSearch
    page with a url like ?type=image&filemime=png, the server-rendered
    results page will give the user only PNG results, etc.
    
    Most of these filters are specific to a given media type. It's not
    valid to ask for video results and then filter by PNG files for
    instance. We show an "invalid search" message to users who arrive
    on the page with invalid type & filter combinations in their URL params.
    
    Previously the PHP search results page would strip out all query params
    except for search term and  "sort" (the only option supported across all
    tabs) when generating HTML form code that allows the user to click on
    tabs and change the search media type in an otherwise static UI.
    
    Now that users are arriving on MediaSearch from the Commons main page
    with "title=Special:MediaSearch" in their URL params, we need to
    make sure we preserve "title" params across tabs as well.
