Accurately report cache sizes before and after purge.

This fixes a merge resolution mishap that occurred in 178be5393fcfaf860c72ba2b9f26acc05b621375.

Also property state units, it's bytes (B) not bits (b), and report kiB when claiming to do so, not MiB.

Fix for 'Cluster is not operational' issue
Don't skip relationships in the cache on rollback.

When loading relationships for a node, and the relationship chain
has been partially loaded, it was possible for another transaction
to make modifications to the next relationship to be loaded for
that node, but without loading it through that node (by loading it
through the other node of that relationship). If that transaction
rolled back it would make the cache skip loading that relationship.
