Added a little patch to prevent crash

from librecad.

Does not crash any longer, but segments still disappear randomly. However, the segments magically reappear if used for a polyline...

from librecad.

In trigger() is called container->optimizeContours(); is reordered all entities in container,
invalidating the "targetEntity" pointer then calling convertPolyline() that require all entities rearranged
and not have care of undoable entities (magically reappear).
I write a new convertPolyline() now can join lines & arcs & I added support for opened polylines

If you find another bug, please, open a new issue
