Some issues with crossing operator ⧉

[naoliv]

I don't remember if there is a ticket about this, sorry.

1)
Validate example1.osm and see two warnings inside Overlapping Identical Natural Areas: 2 ways: A, B and another with 2 ways: B, A

A, B is the same as B, A, and only one message should be displayed (instead 2, as we see now)
The order should not matter here.

2)
Validate example2.osm and see:

There is no warning about the overlapping ways B, C (we should be seeing 3 warnings here: A, B, A, C, B, C)
