Subject: [PATCH] rpc: make sure `gettxoutsetinfo` hash has txids

The key (transaction id for the following outputs) should be serialized
to the HashWriter.

This is a problem as it means different transactions in the same
position with the same outputs will potentially result in the same hash.

Fixes primary concern of #7758.
