Stopgap fix for starting games in landscape orientation.
Save/resume doesn't work when playing in this orientation because it
still starts in portrait mode, pauses the activity before all game
components have been initialized, and then resumes the activity with the
new orientation. Game state is saved whenever the activity is paused, so
it saves a state where game components are null and can't be loaded.
