    PlayerEngineService: Obtain library or metadata info for opened uris
    
    When opening a file from a uri, instead of creating an unknown track,
    try to find the uri on the library or extract the metadata from the
    file.
    This only affects the Open method used by the D-Bus interfaces. The
    various other ways to open a file use different code paths.
    
    Fixes bgo#636071.
