[gnome-shell] Use get_color_from_term() instead of get_background_color_from_term()

[Florian Müllner <fmuellner src gnome org>]

commit 52f5793c9bedbd3400122d51c0eb05571961d899
Author: Federico Mena Quintero <federico gnome org>
Date:   Thu Nov 21 18:24:32 2019 -0600

    Use get_color_from_term() instead of get_background_color_from_term()
    
    The former already checks for term_is_transparent() as its first
    thing.
