In this test we were randomizing different values but minDocCount was hardcoded to 1. It's important to test other values, especially `0` as it's the default. The test needed some adapting in the way buckets are randomly generated: all aggs need to share the same interval, minDocCount and emptyBucketInfo. Also assertions need to take into account that more (or less) buckets are expected depending on minDocCount.

This was originated by elastic#35921 and its need to test adding empty buckets as part of the reduce phase.
Also relates to elastic#26856 as one more key comparison needed to use `Double.compare` to properly handle `NaN` values, this was triggered by the increased test coverage.
