OdbGraph shows confusing log message about node initialization

[ursachec]

OdbGraph should show a No nodes to initialize from current storage message instead of initializing 0 nodes from existing storage - this may take some time

overflowdb/tinkerpop3/src/main/java/io/shiftleft/overflowdb/OdbGraph.java

Lines 120 to 121 in 76faf72

	final Set<Map.Entry<Long, byte[]>> serializedNodes = storage.allNodes();
	logger.info("initializing " + serializedNodes.size() + " nodes from existing storage - this may take some time");

Stumbled upon this small discrepancy while trying out Ocular.
