schemas/vegbien.sql: analytical_stem_view: coordinates: Only use county_centroids coordinates when datasource coordinates are not provided, not also when datasource coordinates aren't geovalid. This also fixes a bug where (NULL) county_centroids coordinates were used for non-geovalid coordinates even when there was no county_centroids match, rather than including the non-geovalid coordinates.
