    app: display profile name in "Color space" field of Image Properties.
    
    "RGB color" is not a color space, only the model. To get full color
    space information, we want to display the model and associated profile
    name.
    Of course, the "Image Properties" dialog also has a tab displaying
    details about the color profile. Still it's better if the general info
    displays not too wrong label contents.
    
    Note: when the used color profile has no name, it will show "(unnamed
    profile)" which is still more informative than just the color model.
