Circle arc wrongly deleting way

[naoliv]

Circle arc is deleting some ways when using it.
See the attached example file. Search for the way tagged with FIXME=circle and use circle arc on it (shift+C)
Note how the way (and the other one) get deleted.

While the way is not properly right (it's crossing itself + the other way), circle arc shouldn't delete them.

raising priority as deleting an uninvolved way is critical

fixed with [o34840:34841] : Show popup if selection cannot be used.

The ways is self-intersecting and thus two of the last three nodes are equal. This was only checked with enabled assertions (-ea).
