When VV is enabled, the waitForVersion() may use the oldest version in the MVCC window as the actual read version, which may often result in the transaction_too_old if the MVCC moved, especially during a readRange(). The change here is to try using a higher read version that is still valid, but not likely to cause transaction_too_old error.
