CToast: Dont pass forward key prop as it's a special prop.

[jasperfirecai2]

If you add a key prop to CToast (e.g. mapping a list of toasts) this warning will show in the console:
key is not a prop. Trying to access it will result in undefined being returned.

As you can see CToast attempts to read and forward the key prop. This should be a differently named prop instead.
