Fixes #2116. Depends on #2134, #2144, #2145. We've known that, especially for sandbox accounts with lots of purchases, the SDK can get flooded with a lot of transactions to process at once. I've been making some improvements for this (like #2115). Another consequence of this behavior, is that we can end up failing due to `StoreKit` throttling us (see #2116): > 2022-12-03 12:31:58.670892+0100 app[673:61074] <SKReceiptRefreshRequest: 0x283edc860>: Finished refreshing receipt with error: Error Domain=ASDErrorDomain Code=603 "Request throttled" UserInfo={NSLocalizedFailureReason=Unified receipt is valid and current, NSLocalizedDescription=Request throttled, AMSServerErrorCode=0} This change avoids that by skipping the refresh if less than 2 seconds have elapsed. I chose 2 to make this a low-ish risk change, with a huge benefit for multiple semi-concurrent requests coming from a big transaction queue.
