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 (pwallet->IsLocked()) {
        throw JSONRPCError(RPC_WALLET_UNLOCK_NEEDED, "Error: Please enter the wallet passphrase with walletpassphrase first.");
    }
}
static void WalletTxToJSON(interfaces::Chain& chain, interfaces::Chain::Lock& locked_chain, const CWalletTx& wtx, UniValue& entry)
{
    int confirms = wtx.GetDepthInMainChain(locked_chain);
    entry.pushKV("confirmations", confirms);
    if (wtx.IsCoinBase())
        entry.pushKV("generated", true);
    if (confirms > 0)
    {
        entry.pushKV("blockhash", wtx.m_confirm.hashBlock.GetHex());
        entry.pushKV("blockindex", wtx.m_confirm.nIndex);
        int64_t block_time;
        bool found_block = chain.findBlock(wtx.m_confirm.hashBlock, nullptr , &block_time);
        assert(found_block);
        entry.pushKV("blocktime", block_time);
    } else {
        entry.pushKV("trusted", wtx.IsTrusted(locked_chain));
