Reorder a g_object_get to not break pidgin.
Review Request #753 — Created June 14, 2021 and submitted
g_object_getwill stop at the first error. Pidgin hadn't yet been updated for
the author-name-color property which lead to the timestamp not being filled out
g_object_getand thus broke all messages in Pidgin 3.
I tested this in the Pidgin tree and then rebuilt it in the talkatu tree.
