Fix stats updates

[benjaminwinger]

Make use of the data offset when calculating the minimum and maximum values of column updates.
Also make use of null data to avoid including stats for placeholder data to avoid including stats for placeholder data used for null values.

Fixes #3572.

I added some tests for testing updates to multiple nodes, as that wasn't previously covered, as well as some negatives (for an issue which I suspected but turned out to something else, but it's probably useful extra coverage, especially since I noticed that few of the existing statistics tests were doing in-place updates that increase the min/max range).
