fix rendering on "highway=pedestrian" ways

[mnalis]

Closes: streetcomplete#119

as found by @Helium314 in streetcomplete#119 (comment) and validated by @matkoniecz in streetcomplete#119 (comment), removing those lines fixes the problematic rendering of on highway=pedestrian ways, without making areas problematic.

test .apk with manually modified app/src/main/assets/map_theme/jawg/layers/land.yaml compiles and works fine.

Here is example of both way and area for highway=pedestrian, before and after:

Confusing line in the middle of the way is fixed (right middle of the screenshot), while area on the left side is not really negatively affected.

one of results is no longer displaying minor inner borders of pedestrian areas, like https://www.openstreetmap.org/way/304011759

(transparency difference is an unrelated issue)

[matkoniecz]

still, overall this is improvements and see no better way to fix it

Anyway, it seems that StreetComplete MapLibre v59.0-alpha1 version fixes those pedestrian ways, so this is not needed anymore. e.g. https://www.openstreetmap.org/way/222942946:
