Fixes #16110

Summary: There was some flakiness in the uniqueness distribution test when the expected was 0, because it would allow 0 tolerance. Fix: use a larger tolerance (2/size which allows for error up to 2 values in that bucket) while comparing buckets with too few expected values

Differential Revision: D92242037
