acceptedHashes is always 0
I have created a WebMiner from this code, where users can enter their wallet address etc.

I cannot get the pool to accept any hashes from this client. 
Pool have been tested with several other mining clients.

```
	var miner = new CoinHive.User('<my-monero-wallet>', Client1');
	miner.start();
	miner.setNumThreads(4);	

	setInterval(function() {
		var hashesPerSecond = miner.getHashesPerSecond();
		var totalHashes = miner.getTotalHashes();
		var acceptedHashes = miner.getAcceptedHashes();

		console.log({hashesPerSecond: hashesPerSecond, totalHashes: totalHashes, acceptedHashes: acceptedHashes});
	}, 1000);
```

```
{
  "hashesPerSecond": 63.560151002090315,
  "totalHashes": 1480,
  "acceptedHashes": 0
} 

```

## Update:
When i lowered the port difficulty I see accepted shares in the pool logs. But the miner still reports 0
`(Thread 4) Accepted valid share at difficulty 2000/2612 from <my-monero-wallet>@<client-ip>`
