Fix team saving in desktop client

I'm not sure why this only recently started becoming a problem; I've
been told this only recently became commonly reported in Help, but the
code I've fixed seems to have been around for a long time. Maybe some
recent change exacerbated it or something.

Anyway, this should make team saving much more frequent, matching how
team saving works in the browser.
