    [Dap.AppleDevice] Fix the total in the progress while sync occurs
    
    It may happen that tracks_to_add gets more songs in the middle
    of a sync so we calculate the total now inside of a lock{} and
    on every iteration.
    
    This was brought up by Gabriel Burt in a review of a patch for
    BGO#620826.
