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:
```
...
     #6  0x00007ffff7a33b86 in __assert_fail (assertion=0x55555783afd2 "pindex", file=0x5555577f2ed8 "llmq/utils.cpp", line=730,

     #21 0x0000555556825f8a in QCoreApplication::exec() ()
...
```

## 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.

src/node/

The src/node/ directory contains code that needs to access node state (state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar classes).

Code in src/node/ is meant to be segregated from code in src/wallet/ and src/qt/, to ensure wallet and GUI code changes don't interfere with node operation, to allow wallet and GUI code to run in separate processes, and to perhaps eventually allow wallet and GUI code to be maintained in separate source repositories.

As a rule of thumb, code in one of the src/node/, src/wallet/, or src/qt/ directories should avoid calling code in the other directories directly, and only invoke it indirectly through the more limited src/interfaces/ classes.

This directory is at the moment sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
