Objects-api and zgw apis geometry coordinates data order

[robinmolen]

Closes #4955

Changes

Changes the order of the geometry coordinates data from [lat, lng] to [lng, lat].

The coordinates that we receive from the map component are in [lat, lng] order. This same order was used when passing the coordinates to the Objects-api and zgw apis backends, but these expect the geometry data to adhere the geoJson geometry data (i.e. the coordinates in [lng, lat] order)

Checked with support - the impression that nobody uses this component + registration backend combination yet, and if wrong data would have been entering the system, they would've noticed by now.
