Hardware back button does not close tab's pages and modals.

[mnasyrov]

Short description of the problem:

The current implementation of a hardware back button (ionic2, beta.6) does not take into account a case when an active tab has its own non-empty ViewController (an opened page, modal or alert). In this case an application is closed after pressing the back button.

What behavior are you expecting?

When a hardware button is pressed then an active item must be closed at the first (alerts, modals and etc.). Only after that an active page of a current page stack should be closed. Application should be closed if there is only a root page without any active child.

Which Ionic Version? 1.x or 2.x
2.x (2.0.0-beta.6-201605132240)

This would apply for Action Sheets as well (invoking the handler for the 'cancel' role).
