[gnome-shell/wip/sasstest: 37/86] shell-app: Remove shell_app_get_faded_icon

[Carlos Soriano Sánchez <csoriano src gnome org>]

commit 81bcd0cffdd02d5f2e32d0e567e328968284b044
Author: Carlos Soriano <csoriano gnome org>

    shell-app: Remove shell_app_get_faded_icon
    
    In previous commit we removed the only use of shell_app_get_faded_icon
    so we can remove the function on shell-app as well.
