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...
const CTxDestination& address = item_it->first;
        const std::string& label = item_it->second.name;
        auto it = mapTally.find(address);
        if (it == mapTally.end() && !fIncludeEmpty)
            continue;
        CAmount nAmount = 0;
        int nConf = std::numeric_limits<int>::max();
        bool fIsWatchonly = false;
        if (it != mapTally.end())
        {
            nAmount = (*it).second.nAmount;
            nConf = (*it).second.nConf;
            fIsWatchonly = (*it).second.fIsWatchonly;
        }
        if (by_label)
        {
            tallyitem& _item = label_tally[label];
            _item.nAmount += nAmount;
            _item.nConf = std::min(_item.nConf, nConf);
            _item.fIsWatchonly = fIsWatchonly;
        }
        else
        {
            UniValue obj(UniValue::VOBJ);
            if(fIsWatchonly)
                obj.pushKV("involvesWatchonly", true);
            obj.pushKV("address",       EncodeDestination(address));
            obj.pushKV("amount",        ValueFromAmount(nAmount));
            obj.pushKV("confirmations", (nConf == std::numeric_limits<int>::max() ? 0 : nConf));
            obj.pushKV("label", label);
