workaround jupyter exception accessing out of bounds argv (#949)

Browse Source 
Under certain circumstances the internal argument parser tries
to determine the program name via sys.arv[0], however the way
we run Cutter and the jupyter integration does not guarantee
that argv is set at all, leading to an exception which avoids
a proper startup.
