Casting crash in native code on iOS when disabling and re-enabling casting

[jmurth1234]

We're experiencing a crashing bug that happens periodically if the user stops and then starts casting within the same app session

output.webm

I'm able to reproduce this with the sample app casting to the default chromecast reciever i.e. CC1AD845
