This change fixes a mistake in the dimension values aggregator. The bug prevented the shortcut in production (not correctness issue) and caused incorrect results in tests when using a block hash that reserves 0 for nulls. This change corrects the issue and randomly uses two types of block hash in tests: one that reserves group 0 for nulls and one that does not.
Closes #137378
