Description (last modified by gh-kliem)

The methods lawrence extension and lawrence_polytope of Polyhedron do not work when the backend is field. 

P = Polyhedron([[1,3], [3,4]], backend="field")
P.lawrence_extension([10,20])
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
TypeError: 'NoneType' object is not iterable

We fix this by properly initializing them with zero rays/lines instead of None.

I think it is good to go. I will wait for the patchbot to finish so I can put it on "positive review".
