Motivation
There are a couple of issues in advanceNonDurableCursors
This happens because highestPositionToDelete calculated when the reader/consumer is caught up is going to be higher than the last confirmed for the of the managed ledger. There is also no point in trying to advance the mark delete position if the reader/consumer is caught up.
