    theme: Don't draw border around symbolic user-icon
    
    Recent commit [1] added a strong light border around user avatar
    icons, in accordance with design mockups.
    
    As a probably unintentional side-effect, the border was also added
    around the symbolic fallback icon, which is displayed whenever the
    user avatar is not available. This doesn't work well with the current
    design, as the strong border makes the subtle fallback icon
    background indistinguishable. Additionally, it doesn't match the
    design mockups for the symbolic avatar icon [2].
    
    Correct this by adding a style class for when avatar image is used,
    and apply the border only for that case.
