[Malleability] Fix ID misuse in ClusterPrefixedMessagesReceivedRecord type

[UlyanaAndrukhiv]

Context

The current ClusterPrefixedMessagesReceivedRecord type has the implementation of Entity on it. Review the ClusterPrefixedMessagesReceivedRecord type to check that ID() method is being used and if so confirm that its ID() returns unique hash of all the content of ClusterPrefixedMessagesReceivedRecord according to encoding rlp rules.

Definition of done

1. Check usages of the ID() method.
2. All structure fields are verified to be included in the hash.
3. Make sure all tests work as expected.

Moved this issue to [EPIC] Refactor herocache/mempool package because ClusterPrefixedMessagesReceivedRecord is internally used by cache.RecordCache with mempool.Backend.
