ETH & ETC uncle blokcs are orphaned. (Fix inside)
### Description

Uncle blocks on Ethereum family coins are getting orphaned.

### Steps to Reproduce

0. Set EthereumConstants.MinConfimations = 100
1. Start Pool
2. Mine ETH or ETC and find uncle block,
3. Wait for the confirmation progress.

### Expected behavior

That uncle block should be clasified as uncle.

### Actual behavior

That block clasified as ORPHAN. Because of the line : https://github.com/coinfoundry/miningcore/blob/df0f06f44eddc8a8b7b5f6aff5f15c667130f079/src/Miningcore/Blockchain/Ethereum/EthereumPayoutHandler.cs#L240

### Reproduces how often

Always.

### Possible Fix

Replacing this line to `if(block.Status == BlockStatus.Pending && **block.ConfirmationProgress > 1**)` should solve the problem.

I think the main problem is, the classifier rouitine cannot reach to the `EthereumConstants.MinConfimations` due to ConfirmationProgress > 0.75 statement. When the ConfirmationProgress hits 0.75, classifies the block as an orphan. I think it should be orphan if ConfirmationProgress > 1
