Fix CTS app security test cases for TV devices.

On TV devices, the app permissions screen uses switches:

Clicking on a permission toggles it on/off, there is no additional
screen that shows the Allow/Deny labels. Also, there is no need to
go back since all permissions are listed on the same screen.

Verified the tests on TV & Pixel 2 test device.
