How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Visit any group or project member pages such as http://127.0.0.1:3000/admin/subscription
2. Scroll down to see the subscription history table.
3. Do one of these two:
   1. Make sure to have at least one future-dated self-managed license created and added. This can get a bit complicated as it requires you to set up CustomersDot with Zuora to create a future-dated license and add it.
   2. Apply this patch to mock future-dated licenses: mock-future-dated-subscriptions.patch
