zcash: Waiting for daemon to connect to peers
### Description

MiningCore connects to Zcash node daemon, but does not allow miners to connect as it claims it is still "Waiting for daemons to connect to peers..."   The node is certainly connected to many peers and is synced up to current block, but for some reason MiningCore believes otherwise.

### Steps to Reproduce

1. Install Zcash Node on Ubuntu
2. Wait for Zcash node to sync up.
3. Configure MiningCore pool with rpc info.
4. Connect to zcash node (successful)
5. See MiningCore hanging, believing the node is not connected to peers.

### Expected behavior

I expect MiningCore to let me mine zcash on it.

### Actual behavior

MiningCore waits forever even though nothing else is reporting a problem.

### Reproduces how often

100%

### Version

0.2.4 Release
Windows 10 x64

### Additional Information

I ran with debug logging, but only got the same loop as the console:

```console

```

It can definitely tell when the daemon is offline vs online, so I'm not sure what else to expect from it... is it parsing the daemon's status incorrectly?
I just ran the daemon with -gen=1 to check, and yes the daemon itself will even start mining and complete Equihash solver runs, so it's definitely synced up and networked.
