Improve Way Accuracy mode will not make overlapping nodes active.

Here's a sample building where the problem occurs:

​http://overpass-turbo.eu/s/siT

[date:"2017-10-12T18:45:02Z"];
way(527587860);
(._;>;);
out meta;

The tool will not make either node on the lower right active. The best thing would be to choose the active node based on the next closest node to the pointer, but something like activating the lowest id node in the overlapping stack would be an improvement over having to switch away from the tool.

The algorithm cannot work with overlapped nodes. It's best to first validate the data to ensure there are no overlapping nodes (the check is at error level) before trying to improve ways.
