dialog: Really set ellipsize mode in subtitle and body

Dialog's subtitle or body could not be properly wrapped, while it's ellipsized when the text's width doesn't exceed the container size. Clutter text has an `ellipsize` property, however in dialog's subtitle and body we have been setting the `ellipsize-mode` property to Pango.EllipsizeMode.NONE that is not present in the underlying GObject. Not being an error in javascript, gjs didn't warn us about this, while at the same time the St.Label's default Pango.EllipsizeMode.END was used. Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/922 https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/531 (cherry picked from commit 3121c9aa29)
