LogFactory - GetLogger should null-check logger name

[snakefoot]

Throw ArgumentNullException instead of throwing NullReferenceException here (When Name is null):

NLog/src/NLog/LogFactory.cs

Line 1015 in 3c16e69

return ConcreteType.GetHashCode() ^ Name.GetHashCode();

Could also consider doing fallback to string.Empty.

Doubted also about this, but I think the change in this PR is good enough
