private static Waypoint createWaypointWithUserNote(final Geopoint point, final String name, final String prefix, final String userNote, final WaypointType type) {
        final Waypoint newWaypoint = new Waypoint("", point, name, prefix, "", type);
        newWaypoint.setUserNote(userNote);
        if (prefix.isEmpty()) {

    }
Waypoint with empty coordinates exist. Update waypointlist from note.
The waypoint has prefix which does not exist, but name of existing waypoint.
So expected size is 2:
- existing waypoint unchanged
- new waypoint with prefix is added.
