Fall back to production if beta receipt is missing (#1031)
When level is .beta, it was relying on beta receipt exclusively without
falling back to production receipt.

This was preventing the sandbox receipt ("production" in TestFlight)
from being read unless the AppUserLevel was explicitly set to .freemium
(0).
