Does this delete the types that 'are' or 'are not' protected?

This deletes data from types that are considered important storage (cache and
cookies) by applying the filter from |filter_builder|. Other data types e.g.
history is deleted completely. I changed the comment to make it more clear

+// completely. The observer will be called twice.
