    coremodel: Don't bind player validation
    
    Since fb9878fac8 starting to play a song from a new set player playlist
    is relatively slow. It is however unneeded to bind validation back to
    the main model song as it is just a short-lived playability check for
    local songs.
    
    Remove the validation property binding to remedy the slowness.
