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...
if (!pfrom->IsAddrRelayPeer()) {
            LogPrint(BCLog::NET, "Ignoring \"getaddr\" from block-relay-only connection. peer=%d\n", pfrom->GetId());
            return true;
        }
        
        
        if (pfrom->fSentAddr) {
            LogPrint(BCLog::NET, "Ignoring repeated \"getaddr\". peer=%d\n", pfrom->GetId());
            return true;
        }
        pfrom->fSentAddr = true;
        pfrom->vAddrToSend.clear();
        std::vector<CAddress> vAddr = connman->GetAddresses();
        FastRandomContext insecure_rand;
        for (const CAddress &addr : vAddr) {
            if (!g_banman->IsBanned(addr)) {
                pfrom->PushAddress(addr, insecure_rand);
            }
        }
        return true;
    }
    if (strCommand == NetMsgType::MEMPOOL) {
        if (!(pfrom->GetLocalServices() & NODE_BLOOM) && !pfrom->HasPermission(PF_MEMPOOL))
        {
            if (!pfrom->HasPermission(PF_NOBAN))
            {
                LogPrint(BCLog::NET, "mempool request with bloom filters disabled, disconnect peer=%d\n", pfrom->GetId());
                pfrom->fDisconnect = true;
            }
            return true;
