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...
UniValue entry(UniValue::VOBJ);
            if (involvesWatchonly || (::IsMine(*pwallet, s.destination) & ISMINE_WATCH_ONLY)) {
                entry.pushKV("involvesWatchonly", true);
            }
            MaybePushAddress(entry, s.destination);
            entry.pushKV("category", "send");
            entry.pushKV("amount", ValueFromAmount(-s.amount));
            if (pwallet->mapAddressBook.count(s.destination)) {
                entry.pushKV("label", pwallet->mapAddressBook[s.destination].name);
            }
            entry.pushKV("vout", s.vout);
            entry.pushKV("fee", ValueFromAmount(-nFee));
            if (fLong)
                WalletTxToJSON(pwallet->chain(), locked_chain, wtx, entry);
            entry.pushKV("abandoned", wtx.isAbandoned());
            ret.push_back(entry);
        }
    }
    
    if (listReceived.size() > 0 && wtx.GetDepthInMainChain(locked_chain) >= nMinDepth)
    {
        for (const COutputEntry& r : listReceived)
        {
            std::string label;
            if (pwallet->mapAddressBook.count(r.destination)) {
                label = pwallet->mapAddressBook[r.destination].name;
            }
            if (filter_label && label != *filter_label) {
                continue;
            }
