fixed empty responses from cyclon bootstrap server

For some reason, the bootstrapping server isn't returning peers for the first request if stochastic process 1 creates only 1 node. This leads to partitions in cyclon. It seems like raise is running n-1 times for me, although the documentations says n times. I'm not sure if it affects everybody, but this seems to fix it for me.

Sorry for the reformatting ;). The real change is increasing the n in the first raise to 2.
