Trac #13744: Bug in modular_decomposition

Paulo Seijas reported the following bug on sage-support [1]

{{{
sage: P = Graph('Dl_')
sage: P.is_prime()
True
}}}

It can be easily fixed by just updating the code with upstream, as it
looks like the bug has been solved since our last update.

That's all this patch does.
