Removed "None" and "Swipe" from screen lock options in the choosing lock screen during setup wizard, because at this step, the user has already chosen to pick a screen lock, hence it's unnecessory to show "none" and "swipe". Implemented this by overriding the DisableUnusablePreferences in SetupChooseLockGenericFragment to disable the insecure lock methods and adding a flag to hide disabled methods for setup wizard.
