To Reproduce:

1. Build and run the app on iOS.
2. Enter some name for the match and click Create.
3. Observe that when CreateMatch is called, this error:

Invalid string passed into NetworkAccessToken ctor, exception:[System.ArgumentNullException: Argument cannot be null.
Parameter name: s
at System.Convert.FromBase64String (System.String s) [0x00000] in <filename unknown>:0
at UnityEngine.Networking.Types.NetworkAccessToken..ctor (System.String strArray) [0x00000] in <filename unknown>:0 ]

is outputted in Xcode and the app gots stuck in a connecting window.

When running the same demo project on 5.3.2f1, I'm getting some response from the server, like :

"JSON Response: [[UnityEngine.Networking.Match.CreateMatchResponse]-success:False-extendedInfo:Failed because of invalid projectid setup. Please verify project setup at https://multiplayer.unity3d.com.]-address:,port:0,networkId:0x0000000000000000,nodeId:0x0000,usingRelay:False"
