Don't reset review state until no permission requires a review.

In a permission review mode we have a per user flag whether a
permission review is required for an app to avoid iteration
over all permissions on an activity start. This state was
incorrectly cleared if a permission review flag is cleared
despite the fact that there may me other permissions requiring
a review.
