This fixes a bug where some xlarge devices weren't showing 3D recent apps. The cause was that the config wasn't guaranteed to be loaded by the time we reach init() in PhoneWindowManager. The fix looks at the property on-demand, which can't happen until after the user sees the home screen, which guarantees the configuration is loaded.
