Description: 
{{OldFormatDeserializer}}’s {{hasNext()}} method can and will consume two 
{{Unfiltered}} from the underlying iterator in some scenarios - intentionally.

But in doing that it’s losing intermediate state of {{lastConsumedPosition}}. 
If that last block, when iterating backwards, only has two {{Unfiltered}}, the 
first one will be returned, and the last one won’t as the reverse iterator 
would incorrectly things that the deserisalizer is past the index block, 
despite still having one {{Unfiltered}} unreturned.
