I was messing around with min relay policies and found that under certain circumstances the mempool will accept things, then not relay to any peers.

Example made using wallet:
Transaction of size 6195, fee of 619 satoshis, minrelay of 100 satoshis per kvB. Mempool logic allows it:

```
        // No transactions are allowed below minRelayTxFee except from disconnected blocks
        if (!bypass_limits && nModifiedFees < ::minRelayTxFee.GetFee(nSize)) {
            return state.DoS(0, false, REJECT_INSUFFICIENTFEE, "min relay fee not met", false, strprintf("%d < %d", nModifiedFees, ::minRelayTxFee.GetFee(nSize)));
        }
```
and lets it into mempool

but in net_processing.cpp:

```
                    if (filterrate && txinfo.feeRate.GetFeePerK() < filterrate) {
                        continue;
                    }
```
this gets hit because the computed feerate is insufficient(printing I added):
```
0.00000099 BTC/kB
```

I'm not super at arithmetic so I'm opening this up in case someone has an easy fix. 

let me also get a reproducible test failure with this...
throw JSONRPCError(RPC_INVALID_ADDRESS_OR_KEY, "Invalid or non-wallet transaction id");
    }
    const CWalletTx& wtx = it->second;
    CAmount nCredit = wtx.GetCredit(*locked_chain, filter);
    CAmount nDebit = wtx.GetDebit(filter);
    CAmount nNet = nCredit - nDebit;
    CAmount nFee = (wtx.IsFromMe(filter) ? wtx.tx->GetValueOut() - nDebit : 0);
    entry.pushKV("amount", ValueFromAmount(nNet - nFee));
    if (wtx.IsFromMe(filter))
        entry.pushKV("fee", ValueFromAmount(nFee));
    WalletTxToJSON(pwallet->chain(), *locked_chain, wtx, entry);
    UniValue details(UniValue::VARR);
    ListTransactions(*locked_chain, pwallet, wtx, 0, false, details, filter, nullptr );
    entry.pushKV("details", details);
    std::string strHex = EncodeHexTx(*wtx.tx, pwallet->chain().rpcSerializationFlags());
    entry.pushKV("hex", strHex);
    if (verbose) {

        TxToUniv(*wtx.tx, uint256(), decoded, false);
        entry.pushKV("decoded", decoded);
    }
    return entry;
}

    std::shared_ptr<CWallet> const wallet = GetWalletForJSONRPCRequest(request);
    CWallet* const pwallet = wallet.get();
    if (!EnsureWalletIsAvailable(pwallet, request.fHelp)) {
        return NullUniValue;
    }
