Added fallback for top members (#1856)

* Added fallback for top members

refs https://github.com/TryGhost/Team/issues/469

We do not have open rates for a member until we've sent at least 5
emails. In order to still display a top members section for sites which
have not sent that many newsletters, we fallback to paid members,
ordered by created_at. This effectively gives us our oldest members,
which are currently paid.
