fix: editing coordinates manually would not be saved

The primary coordinates is a two-elements Array in Point.coordinates,
but FormBuilder does not know how to edit an Array, so we edit the
`ui._latlngs` instead.

The proper fix would have been to teach FormBuilder how to edit an
Array, but that path is way longer, and given we plan to refactor
it totally, let's wait for that.
