Daemon crashes in InvalidChainFound if genesis block fails validity check

Daemon (0.10 branch, commit 047a89831760ff124740fe9f58411d57ee087078) crashes in InvalidChainFound when run with empty blockchain and genesis block is invalid (fails validity check).

GDB stacktrace:

LogPrintf("InvalidChainFound:  current best=%s  height=%d  log2_work=%.8g  date=%s\n",
      chainActive.Tip()->GetBlockHash().ToString(), chainActive.Height(), log(chainActive.Tip()->nChainWork.getdouble())/log(2.0),
      DateTimeStrFormat("%Y-%m-%d %H:%M:%S", chainActive.Tip()->GetBlockTime()));

chainActive.Tip() is NULL, possibly because we don't have an active chain/chain tip as the genesis block verification has just failed.
