fix #18420: Move node onto ways not working anymore
sort result from NavigatableComponent again using higher precision
improve handling of multiple target ways with similar distance so that the node is added to the closest segment and also to segments with almost the same position but NOT to segments further away or with a similar distance but different position.
fix possible error when multiple nodes are selected
use LinkedHashMap for field data to avoid random results from iterator (hope this fixes the unit test problems)
