Title: Fix for #365: Behaviour when logging null arguments 

Parsing a [null] parameter in for example logger.Info("Testing null: {0}", null); will result in not logging an event. A
System.NullReferenceException would be thrown causing the entire logEvent NOT to be logged. This behavior is different from prior versions. This fix will restore the previous behavior.
