poll more often for inactive closed groups

the issue is that when you start the app, a closed group active at is
maybe a day old.
so you poll for this pubkey.

if the call is a success, all good, you get the latest messages and
update the active_at.
but if the first call fails (even after retrying), this group will be
marked as inactive and will be polled only a tiny little bit until we
get new messages.

So this commit make sure that we poll more often for closed groups which
are considered inactive
