"create circle" creates enormous circles of ways with three nodes

[malenki]

Issue: as mentioned in the subject

Circles created from not closed ways with three nodes have a diameter several times bigger then the length of the origin way.
If you try this trick with an exactly straight way no matter how short the circle has a little more than equator length.

In 6669/josm:

see #9565 - don't consider infinite coordinates as valid
