This PR fixes a bug in the `WHERE` clauses in the transportation layer generalization tables for zoom 10. The intended behavior of the layer is to suppress `highway=tertiary` and `highway=tertiary_link` at zoom 10 and lower. However, due to this bug, these objects were not suppressed as intended, because an `OR` was used in the SQL where an `AND` was needed instead.
This bug was inadvertently introduced in #1172😞
