Unused `LogLevel::Debug` and a place where it can be used

[NexiusTailer]

LogLevel::Debug in vlogLnInternal (here) doesn't have even a single place where it's actually used. However, at least one place where it can be used is the following code:

open.mp/Server/Components/LegacyNetwork/legacy_network_impl.cpp

Lines 579 to 584 in e6c5de0

	#ifdef _DEBUG
	if (network->inEventDispatcher.count() == 0 && network->rpcInEventDispatcher.count(ID) == 0)
	{
	network->core->printLn("Received unprocessed RPC %zu", ID);
	}
	#endif

So it should probably omit #ifdef _DEBUG check and use network->core->logLn(LogLevel::Debug, instead.

Done.
