Cannot rename when connected to IoT Device

[GregPettyjohn]

For IoT, I was able to connect but then subsequently ran into a failure when requesting the device name. I sent along the stack trace to Hirsch and he was able to reproduce this:
[] There was an error deserializing the object of type Microsoft.Tools.WindowsDevicePortal.DevicePortal+DeviceName. Encountered unexpected character '<'.
