Need warning before unsubscribing from a private stream.

[Tignus]

This issue has been fixed in the webapp.

I'm opening it here so it can be tracked on the mobile app.

Right now it is quite easy to get locked out of your own private stream.

@arijitghosal03 please post a comment describing your proposed approach when you're ready. I can assign the issue to you once you have a rough plan. Thanks!

@alya
This problem was already fixed in the web app design. My plan intends to implement the same warning notification through some frontend conditional code which will rest of the operations same as it is if the user chooses "Confirm" else (i.e. "Cancel") will redirect him to the previous window.
The issue can be thus resolved by these code changes and I will be glad to work on this.
Thank You

Thanks! @chrisbobbe @gnprice FYI, in case you have any feedback on the above plan.
