BUG-5280: fix problems identified by integration tests

Switching the integration test suite has flushed out couple
of problems in the implementation, notably:

- wrong formatting placeholder
- unhandled requests during replay
- uninitialized path in AbstractReadTransactionRequestProxyV1
- missing sequence number bump in local commit case
- wrong writeObject() in ReadTransactionSuccessProxyV1
- IllegalStateException thrown instead of TransactionChainClosedException
- attempt to create history=0 on the backend
- mismatched sequences during preCommit message replay
- ConcurrentModificationException during localAbort()
- missing upcalls to LocalHistory concretizations when transactions abort
  and complete
- incorrect order on enqueue/send, leading to unpaired responses
