Title: Fixed notification comparasion when title or content is nil value.

When comparing two notifications, if both title strings or both content strings are nil values, notifications should be equal.

In Objective-C two nils are not equal, but in this situation, I think it is more sematicaly correct to assume that nil string are equal.
