Description

Steps to be able to reproduce it :

• have a heap of 1Gb
• have a saved key cache without the SSTables

When looking at KeyCacheSerializer.serialize : it always writes a Boolean
When looking at KeyCacheSerializer.deserialize : no Boolean is read if SSTable is missing...

In case of a promoted index, RowIndexEntry.serializer.skip(...) should be called rather than RowIndexEntry.serializer.skipPromotedIndex(...) (again for symmetry between serialization/deserialization)

Attached is a proposed patch
