Effort, Reward, Type, Status problem with API
### Description

Running Parity and MiningCore, mining seems to be fine but;
When I get the results via **WebAPI**, 

**But when I check the database, i saw that theese values are null/0 in database too"

http://prntscr.com/lmf9ws

1. Effort is **always null**
2. Reward is **always 0**
3. Type is **always null**
4. Status is **always pending**

Is there something that I miss?

### Steps to Reproduce

1. Rent hashpower from NiceHash
2. Mine and find blocks,
3. Check the block from API

### Expected behavior
1. Effort should be some value
2. Reward should be the block reward
3. Type should be block/uncle
4. Status should change

### Actual behavior

1. Effort is **always null**
2. Reward is **always 0**
3. Type is **always null**
4. Status is **always pending**

### Reproduces how often

Always

### Version

Dev #484 
Running on windows 10
