Fix uninstall button can't click problem

Install CtsVerifier.apk and CtsEmptyDeviceAdmin.apk. When CtsEmptyDeviceAdmin is active device administrator, “Uninstall” button can’t click, we can’t uninstall the apk.

Compared with Android T, the ability to uninstall Active admin's apk is disabled by default on Android U. Make this cts test pass after modifying the setup code
