The calculation for num_nulls in the incremental stats code path initialized the counter to -1 instead of 0. This meant that, if there were no nulls (reasonably common), the num_nulls counter would be set to -1, indicating unknown, rather than 0. This simply fixes the initialization and updates the tests.
