[FLINK-6662] [errMsg] Improve error message if recovery from
RetrievableStateHandles fails
When recovering state from a ZooKeeperStateHandleStore it can happen that
the deserialization
fails, because one tries to recover state from an old Flink version which
is not compatible.
In this case we should output a better error message such that the user can
easily spot the
problem.
