Fix flaky test caused by Uninstall activity
The uninstall operation will trigger a system dialog. The test
can't monitor the activity belonging to other process. The only we can
do is to scan the whole screen 1 time 1 second until either the
expected UI object is found or timeout that is 30 seconds.
This patch uses
* UiDevice.wakeUp to power on.
* UiDevice.pressMenu to unlock keyguard
* UiDevice.pressBack to dismiss other system alert window
* UiDevice.pressHome to back to home screen
* UiDevice.waitForIdle
