fix: possible assert call if nHeight in CDeterministicMNList is higher then Tip (#5590)
## Issue being fixed or feature implemented
fix: possible assert call if nHeight in CDeterministicMNListDiff is
higher than Tip
    
Example of new log:
```
2023-09-28T17:35:50Z GetProjectedMNPayeesAtChainTip WARNING pindex is nullptr due to height=914160 chain height=914159
```
    
instead assert call:
```

```

## What was done?
ClientModel returns now a pair: MNList and CBlockIndex; so, we always
know the which one has been used even if current chain is switched.

## How Has This Been Tested?
Run on my localhost from `c034ff0c2606142ba3e8894bc74f693b87374e5c` -
aborted with backtrace like above.
With both of commit - no assert more.
