Improve robustness of adding points to topology (#3280)

When multiple edges are within tolerance from the added point,
give preference to snapping to the one which contains a point
projected to it.

Also, make sure to sort nodes and edges by distance before
considering them for matching or snapping, which is what
was done in previous versions.
