Bug: joining a second call with other device settings doesn't change device info of call

[LucasMaupin]

When you join a call and then want to "Add Call" and select the device input and output you want and then press join, it will still show that you have default device under devices when you are in the new call. But it still seems like it took the setting when you joined because if you then change it to the one you wanted, you can't press "save"
