Update git submodules

* Update extensions/MediaSearch from branch 'wmf/1.38.0-wmf.17'
  to 49a1b7827fe0a73d679aa176ce4d386856b93000
  - Merge "Undo update to the way the search interface is set" into wmf/1.38.0-wmf.17
  - Undo update to the way the search interface is set
    
    We only intend to deploy this if we fail to
    successfully run the maintenance script in time,
    converting all existing preferences to their new
    equivalent.
    If that doesn't happen, we need to merge this to
    undo the changes, since people would otherwise
    find their preferences no longer respected.
