When a client sets WM_NAME (client->alt_name) but doesn't set _NET_WM_NAME
(client->name), we give alt_name to lua when c.name is used. However, we still
emitted property::alt_name instead of property::name to lua. Obviously, this
breaks stuff.
(The same applies to client->alt_icon_name)
I noticed this via feh whose tasklist entry wasn't refreshed when multiple
images were displayed and I switched to the next one.
