[gnome-shell/wip/fmuellner/minor-bug-fixes: 9/9] iconGrid: Remove unreachable code

[Florian Müllner <fmuellner src gnome org>]

    iconGrid: Remove unreachable code
    
    Throwing an exception already aborts a function, so there's no need
    for a return statement in that case.
    
    Spotted by eslint.
