Exclude invalid ways

Invalid ways can be either:
- truly invalid (in which case there's a different analyser that gives a better warning)
- the result of a partially downloaded way (in which case we shouldn't warn), example: a valid closed way with only 2 nodes in the extract gives an overlapping linestring as the 'outside the extract' nodes are missing)

Also remove a bad copy-paste
