Adding stopWithTask tag and onTaskRemoved to the service

[mathBordin]

I noticed that my application wasn't killed because the foreground service continued to run after closing the app, even calling stopService on componentWillUnmount. So, I made this change to solve this problem by adding the stopWithTask tag on the AndroidManifest.xml and calling stopSelf inside onTaskRemoved.

You can check for this problem by verifying that the application's PID is the same after reopening it. In fact, it continues to run even when it is closed.

@mathBordin It's killing the notification but when I checked the app status on the app info it seems app still working in the background and the option 'force stop' is available. And I checked it starting the service causing this without foreground service when I kill the app there is no 'force stop' option available. I think it's not exactly killing the service
