This commit fixes a bug where the city report returned `N/A` entries. The functions that build imported data queries were using SQL `COALESCE`, assuming city data is `NULL` when unknown, when actually its unknown value is `0`. This commit addresses the problem using SQL `NULLIF` combined with the previous `COALESCE` call. With this change both `0` and `NULL` are treated as unknown. Since 1cb07ef cities can be `NULL`, but previously we saved `0` as unknown. Closes #1960
