EntryRetrievalCommand must enlist the transaction

When entries are read in transactional cache through cache.filterEntries() and there are no other operations in this transaction, new LocalTransaction is created and registered in the TransactionTable but this is never enlisted; TxInterceptor.visitEntryRetrievalCommand does not enlist it.

Since unregistration from TransactionTable relies on enlistment, the LocalTransaction stays there until it is cleaned up.
