Fix: disable tests that depend on Google Maps key

The two disabled tests fail due to not having a working Google Maps API
key. The UI fails trying to load the map, and that JavaScript error
breaks the UI interactions and navigation.

I'm temporarily disabling the tests until we fix the UI or provide a
valid API Key.
