Merge #15999: init: Remove dead code in LoadChainTip
fa86c8aec6 init: Remove dead code in LoadChainTip (MarcoFalke)
Pull request description:
`LoadChainTip` sets `::ChainActive()` based on `pcoinsTip`'s best block. `LoadChainTip` is never called when that block is null, so we can remove all code from within that method that is only executed when that block is null.
Fixes #15967 Inconsistent locking behavior in LoadChainTip

utACK fa86c8aec611a9b9d2f53960c92419cf2a8bb92d. LoadChainTip isn't called currently when pcoinsTip best block is null due to this line:
