[gnome-music] view: Set model on the view after all insertions happened

[Carlos Garnacho <carlosg src gnome org>]

    view: Set model on the view after all insertions happened
    
    This avoids the burst of ::row-inserted signals, and the resulting side
    activity. Inserting all items at once when there's still no connected
    handlers will be faster.
