Subject: [PATCH] Update error message to match new arc dialog

We now provide arc end points and interior angle, so we cannot check for
null radius in the same fashion.  Instead, the starpoint==endpoint
indicates a zero radius

Fixes https://gitlab.com/kicad/code/kicad/issues/10714

(cherry picked from commit ef94f31204048f44d2dddb409a3b8c27a87a564d)
