Tommi c4dd03dfcb Remove kUnknown as a possible value for IceCandidateType. 
Subsequently also tighten IceCandidateType error checking.
The Candidate type in `cricket` should be using something similar
(currently using a string for the type), so I'm making sure that
types that we have already, align with where we'd like to be overall.
Possibly we can move IceCandidateType to where Candidate is defined.
