Cannot read property 'unsubscribe' of undefined!!!

[dsl-src]

I use authorization component which checks if user is authorize to see protected page where I have and SimpleNotificationsComponent. In case of unauthorized attempt, the authorization component uses Router and navigates to login page. And in that case I got:

Unhandled promise rejection TypeError: Cannot read property 'unsubscribe' of undefined(…)

which leads to NotificationComponent and:

ngOnDestroy()
{
this.addToastSubscriber.unsubscribe()
this.clearToastsSubscriber.unsubscribe()
}

It is probably because of component not being initializes in ngOnInit.

The listener that is trying to unregister doesn't appear to be part of the toaster component. Can you please create a small plunkr that demonstrates this behavior?

I made the Pull Request to fix this problem.
Please accept it. I really like this library but this problem does not allow her to use.
