Don't revert to nearest address - always use exactly where the user right-clicked

This should solve two problems:

1. "No address found". If there's no address found, that's okay, we can use Nominatim to get the feature name (it could be a park).

1. Putting the marker of a found address far away from the user's desired location on which they right-clicked (this shouldn't happen, the user's desired location is the most important location).
