hotfix: some symbol layers not showing up (v1.12.1) (#601)

Layers that don't have name properties do not need to be localized (e.g. highway numbers).
Localizing them was overriding their properties, which caused them to not show up on the map.

J= WAT-5275
TEST=manual

verified on test-site that road shields and route markers now show up, and place names are still localized as expected.
