Don't wait for TEvReadSetAck from non-existent tablets (#17913)

[Alek5andr-Kotov]

Changelog entry

Moved changes from #17913

Issue #17915

The PQ tablet forgets about the transaction only after it receives a TEvReadSetAck from all participants. Another shard may be deleted before the PQ completes the transaction (for example, due to a split table). As a result, transactions are executed, but remain in the WAIT_RS_ACKS state.

If the PQ tablet sends a TEvReadSet to a tablet that has already been deleted, it receives a TEvClientConnected with the Dead flag in response. In this case, we consider that we have received a TEvReadSetAck.
