Making the event itself writable is not enough, it won't make the actual taglist in the event writable as well. Instead, just make a copy of the taglist and then create a new tag event from that if required, replacing the old one. Before we would inadvertently modify taglists upstream elements might still be holding on to. Add unit test for this as well. https://bugzilla.gnome.org/show_bug.cgi?id=762793
