[ndnSIM] Exception while creating face (converting face-uri to canonical form)

Hi Anil

FaceUri needs to be in canonical form as shown on
http://redmine.named-data.net/projects/nfd/wiki/FaceMgmt#FaceUri .
Otherwise, software may attempt to resolve the hostname with DNS, and that
would fail unless you have a DNS server within the simulated network.

Yours, Junxiao
