[gnome-photos] Simplify showing the preview controls for the first time

[Debarshi Ray <debarshir src gnome org>]

commit 949246eab98663c8d84d575cbe785f982f4c5de0

    Simplify showing the preview controls for the first time
    
    Showing the controls requires having the model, which is independent
    from loading the pixels and setting the GeglNode. We already have the
    model. Therefore, call the show method immediately after setting the
    model.
