Paul Fitzpatrick 1ce5e98996 (core) suspend a team site after an AppSumo refund
Summary:
This suspends service to a team site for which an AppSumo refund has been made, and nudges users to their free personal account.

I expect that a refund request would fail for a site where user is also paying us for extra seats.

Test Plan: tested manually
