cc15c5bfd1eb3903de246c124702a7c66c687008 fuzz: don't allow adding duplicate transactions to the mempool (Suhas Daftuar)
Pull request description:
Filter duplicate transaction ids from being added to the mempool in the `partially_downloaded_block` fuzz target.
I think a prerequisite for calling `CTxMemPool::addUnchecked` should be that the underlying txid doesn't already exist in the mempool (otherwise `addUnchecked` would need a way to return failure, which we don't currently have).
