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...
target_confirms = request.params[1].get_int();
        if (target_confirms < 1) {
            throw JSONRPCError(RPC_INVALID_PARAMETER, "Invalid parameter");
        }
    }
    if (ParseIncludeWatchonly(request.params[2], *pwallet)) {
        filter |= ISMINE_WATCH_ONLY;
    }
    bool include_removed = (request.params[3].isNull() || request.params[3].get_bool());
    const Optional<int> tip_height = locked_chain->getHeight();
    int depth = tip_height && height ? (1 + *tip_height - *height) : -1;

    for (const std::pair<const uint256, CWalletTx>& pairWtx : pwallet->mapWallet) {
        CWalletTx tx = pairWtx.second;
        if (depth == -1 || tx.GetDepthInMainChain(*locked_chain) < depth) {
            ListTransactions(*locked_chain, pwallet, tx, 0, true, transactions, filter, nullptr );
        }
    }
    
    
    UniValue removed(UniValue::VARR);
    while (include_removed && altheight && *altheight > *height) {
        CBlock block;
        if (!pwallet->chain().findBlock(blockId, &block) || block.IsNull()) {
            throw JSONRPCError(RPC_INTERNAL_ERROR, "Can't read block from disk");
        }
        for (const CTransactionRef& tx : block.vtx) {
            auto it = pwallet->mapWallet.find(tx->GetHash());
            if (it != pwallet->mapWallet.end()) {
