Fix Settings crash when click uninstall button
When mPackageName is null, mFinish is true. OnResume() doesn't
invoke refreshUI(). It causes uninstall button is still enabled.
The solution is hiding AppButtonsPreference when mFinish is true.
Fixes: 138524326
Test: make RunSettingsRoboTests ROBOTEST_FILTER
