After enabling smoke tests, we're seeing "PreconditionFailed Message: At least one of the pre-conditions you specified did not hold" errors which come from setting the If-None-Match pre-condition here.

This came about because the smoke tests were inserting a large volume of data with writeCount=1. This means that we were in a situation where we had a large number of PutObjectAsync requests open at a time.

The issue ultimate comes about because we're not properly assigning the correct key suffix. I suspect this is because some writes are happening on different threads, but we should confirm this as part of this ticket.
