[nautilus/gnome-3-28] tag-manager: Use a constant for the tag name

[António Fernandes <antoniof src gnome org>]

commit 1a054be5ffa26cea493703a2f5c726e5451b477a
Author: António Fernandes <antoniof gnome org>
Date:   Mon Mar 5 15:08:39 2018 +0000

    tag-manager: Use a constant for the tag name
    
    This ensures all uses of the tag id use the same string. It also makes
    it easy to change the tag id, as we are doing next commit.
    
    
    (cherry picked from commit 7935ee5b5cf9cbf8680ef2d847a3a54d5b2e85b6)
